2.1 Background information

Kafire is a Senufo language from the Central Senari group, spoken in three sub-prefectures (Sirasso, Nafoun and Kanoroba) in the department of Korhogo in Northern Côte d’Ivoire. It is as yet undescribed, apart from the lexical and phonological description in Silué Reference Silué2017. This study is part of an ongoing documentation project that relies on an analysis of a corpus of traditional narratives (Silué In prep.b), complemented with elicitation sessions with native speakers. Our examples are either constructed in consultation with native speakers during elicitation sessions or extracted from the narrative corpus under development (in which case reference is given to the relevant story in the corpus and the segment in the story).

This study is the first formal description of agreement phenomena in Kafire. Silué Reference Silué2017 gives a brief sketch of the noun class system but does not describe the phenomena that we discuss here. Descriptions of noun class systems can be found in grammars of other Senufo languages (Carlson Reference Carlson1994, Dombrowsky-Hahn Reference Dombrowsky-Hahn2015), as well as in formally oriented studies by Baron Reference Baron2016 (for Nafara) and Traoré & Féry Reference Traoré, Féry, Bennett, Angeles, Brasoveanu, Buckley, Kalivoda, Kawahara, McGuire and Padgett2018, Traoré Reference Traoré2020 (for Tagbana). Yéo Reference Yéo2012 is a comparative study of data from several languages.

Senufo languages are traditionally classified as a subgroup within the Gur family; more recently, they have been treated as a family related to Gur within the Volta-Congo group (Hammarström et al. Reference Hammarström, Forkel, Haspelmath and Bank2021). Noun class systems of Gur languages have received considerable attention (Nicole Reference Nicole1999, Miehe & Winkelmann, eds. Reference Miehe and Winkelmann2007, inter alia), but the extent to which they function in the same way as in Senufo languages remains unknown.

2.2 Elements that agree in noun class

Each noun is associated in Kafire with one of five noun classes (we leave aside for the moment cases of polysemy where the same noun is associated with more than one class depending on its meaning; we return to them later). The noun class is manifested in the choice of an obligatory noun class marker, in the form of the demonstratives, as well as in the form of several types of pronouns.

Different series of noun class markers are used in definite and indefinite contexts, and three of the five classes have different markers in the singular and in the plural. Table 1 lists the indefinite noun class markers, arranged in a way consistent with their description for some of the related Senufo languages (Welmers Reference Welmers1950, Carlson Reference Carlson1994, Baron Reference Baron2016). Our arrangement differs from the one adopted in Miehe & Winkelmann, eds. (Reference Miehe and Winkelmann2007) for Gur and those in Traoré & Féry Reference Traoré, Féry, Bennett, Angeles, Brasoveanu, Buckley, Kalivoda, Kawahara, McGuire and Padgett2018 and Traoré Reference Traoré2020 for Tagbana in that it does not treat the singular and the plural markers as separate classes. Definite noun class markers are listed in Table 2.

Table 1

Indefinite noun class markers of Kafire.

Table 2

Definite noun class markers of Kafire.

All class markers are monosyllabic and have a CV structure, except for the plural markers of Classes 1 and 3, which consist of two syllables and are of the shape CVCV. In the case of monosyllabic markers, the distinction between the indefinite and the definite marker depends on the nature of the marker’s vowel. In the indefinite, the vowel can have different realizations depending on the last vowel of the stem. In the definite marker, the vowel is always realized as -i, and tends to be omitted at the end of the word. In the case of two-syllable markers (CVCV), both vowels are realized as -e, and the indefinite and the definite marker only differ in tone. We treat the definite markers as synchronically non-decomposable, even though they seem to derive, historically, from a combination of the indefinite (or the unmarked) class marker with the vowel -i.

Demonstratives are another element sensitive to class. There are two demonstratives in Kafire, a proximal and a distal one; both agree in class with the noun phrase. The forms of the demonstratives are listed in Tables 3–4; note that when the demonstrative follows the noun phrase, it must be preceded by a noun class marker.

The proximal demonstrative.

Table 4

The distal demonstrative.

Finally, several series of pronouns agree in noun class with their antecedent; Tables 5–6 list the corresponding forms of regular anaphoric and so-called emphatic anaphoric pronouns.

Emphatic pronouns.

2.3 The puzzling agreement with adjectives

A crucial property of the agreement system that has already been introduced in Section 1 is the exceptional behavior of a number of adjectives which are associated with their own inherent class (Class 2 for kpɔ́ ‘big’, fálá ‘lazy’, kálá ‘clownish’; Class 3 for pī ‘little’, kpēlē ‘short’, prō ‘idiot’). These adjectives differ from regular adjectives in imposing their own class on the entire noun phrase: the noun phrase agrees with the adjective irrespective of the class of the head noun. This results in a seemingly paradoxical pattern: the class value contributed by the head noun is overruled, for the purposes of agreement, by the value of an adjectival modifier.

The difference between the two types of adjectives is illustrated in (6)–(8). All adjectives follow their head noun and precede the noun class marker. Regular adjectives have no effect on the class of the noun phrase: the class marker in (6) is the one normally associated with the noun nà̰ ‘man’. The adjectives in (7)–(8), however, change the class of the entire noun phrase: the noun phrase becomes Class 2 or Class 3, depending on the adjective.

The account we develop in the following sections addresses this split in the behavior of regular versus class-assigning adjectives. We suggest that both nouns and class-assigning adjectives are associated with class information, and both can pass on their class information to the noun phrase. The class information is encoded as part of the lexical entry of the noun or the adjective. Regular adjectives, however, are not associated with any class.

When a class-assigning adjective contributes class information that is not consistent with that of the head noun, the information contributed by the adjective takes precedence over that contributed by the noun, and the class associated with the adjective overrules the class associated with the noun. In our formal account (which we present in full in Section 4), we achieve this effect by making the class specification on the noun optional, so that it can be overruled by the class information contributed by a class-assigning adjective.

Making the class specification on nouns optional allows us to account for another non-trivial property of the noun class system of Kafire: the semantically motivated use of noun class markers. As we already mentioned, and as we discuss in detail below, some of the class markers can combine with nouns of a different class provided that they modify the noun’s denotational meaning (Class 2 markers, for example, can attach to nouns of other classes in an augmentative reading). Such flexibility is allowed by the optionality of the class specification on nouns. Our account treats the relevant class markers as polyfunctional: in a neutral interpretation, they function as determiners that agree with the noun phrase, but they can also be used to alter the noun’s meaning, irrespective of the noun’s class.

Before we outline the details of our formal account, we discuss, in general terms, our treatment of the syntactic structure of the Kafire noun phrase, as it differs, as we already mentioned, from some of the previous accounts of noun class agreement in Senufo.

3.1 Noun class markers are determiners, not suffixes

We depart in our treatment from traditional accounts of Senufo noun class markers (Carlson Reference Carlson1994: 76; Manessy Reference Manessy1996a, Reference Manessy1996b; Yéo Reference Yéo2012; Traoré & Féry Reference Traoré, Féry, Bennett, Angeles, Brasoveanu, Buckley, Kalivoda, Kawahara, McGuire and Padgett2018; Traoré Reference Traoré2020). Instead of analyzing them as nominal suffixes, we treat them, with Baron Reference Baron2016, as clitics attaching to the last element of the noun phrase, which can be a noun or an adjective. Our evidence for this analysis comes from the way adjectives are integrated into the noun phrase.

Modifying adjectives always follow the nominal head. In this position, they are freely ordered, i.e. the ordering of adjectives is not determined strictly in terms of semantic notions such as color or size. The order of adjectival modifiers is defined instead by information-structure considerations: adjectives conveying new information and adjectives that are in focus are placed before adjectives conveying discourse-old information. Crucially, when the noun is modified by more than one adjective, the class marker follows the final adjective, as represented in (9)–(10).

The free ordering supports our idea that what are traditionally analyzed as nominal suffixes are in fact clitics attached at the end of the noun phrase. This treatment makes it unnecessary to stipulate the existence of complex patterns of adjective incorporation or noun-adjective compounding, for which we find no evidence in Kafire.

Compounding is commonly assumed in descriptions of various Gur languages as an explanation for the post-adjectival position of the noun class marker (Carlson Reference Carlson1994: 164; Dombrowsky-Hahn Reference Dombrowsky-Hahn2015: 228; Creissels Reference Creissels and Güldemann2018: 733–736, inter alia). It is also assumed, based on phonological evidence, in the study of another Senufo language, Tagbana, in Traoré Reference Traoré2020; see also Rialland et al. Reference Rialland, Traoré and Féry2021. We believe that the phonological evidence is compatible with the analysis of noun class markers as clitics, if they are viewed as belonging to the same phonological word as their host. Syntactic evidence for compounding is based on the detached position of the noun class markers, which we believe follows more naturally if they are analyzed as clitics, for the following reasons.

First, the number of adjectives following the head noun does not seem to be restricted, contrary to what is expected of typical compounds. The order of the adjectives is, moreover, flexible (see again the examples in (9)–(10)), and changes of order produce little semantic effect. Second, the construction shows no semantic effects typical of compounding or incorporation in other languages, and the noun-adjective combinations show no evidence of lexicalization. Finally, there is no alternative in Kafire to placing the noun class marker after the last adjective. The compounding analysis would lead us to assume, rather unusually, that Kafire simply lacks an alternative to compounding, or that it lacks altogether an adjectival modification construction that does not involve compounding. The clitic analysis does not require us to make such an exotic assumption.

The structure in (11) shows our analysis of the example in (9a). We assume that multiple adjectives (AP) can freely modify a noun phrase (NP); in this particular example, there happen to be three of them. The class marker is a determiner (D) that attaches at the end of the noun phrase, turning it into a full-fledged, class-marked noun phrase ready for use in discourse (DP). (Unlike in English, we find no evidence in Kafire for a separate specifier position, hence we assume that D′ coincides with DP; this assumption is, however, in no way crucial to our account.)

To summarize, we suggest that noun class markers function as determiners that attach to the noun phrase and turn it into a DP. The markers’ obligatoriness explains why they have been mistaken for nominal suffixes in previous studies. In the next subsection we further illustrate this analysis and discuss an important irregularity in the appearance of class markers with certain nouns.

3.2 Some nouns have inherent determiners

A number of nouns do not take an overt indefinite marker, yet such a marker appears when the noun is definite or when it is modified by an adjective. Nouns that are characterized by such behavior are rather diverse in form and meaning, cf. pà̰ ‘monitor lizard’, bà ‘sheep’, síkà ‘goat’, ʃɔ̰́ ‘person’, pɔ̰̄ ‘dog’, fjā ‘fish’, nɔ̰́ ‘cow’, pìcá ‘lady’, càrà ‘lion’, tésɔ̰́ ‘toad’, sèɟɔ̰́ ‘panther’, mà̰zà ‘peanut’, kɔ́rɔ́ ‘canoe’, kàʃì ‘war’. They also include recent borrowings (which typically come from Jula, a Mande language without noun classes, and more rarely from French), cf. nɛ̀ʔɛ̀só ‘bike’ or màrfá ‘gun’ (from Jula).

In (12a), the noun pà̰ ‘monitor lizard’ appears without an overt determiner when used in a non-specific indefinite reading; (12b) shows that it combines with a definite determiner in a regular way. (We leave aside here the question of the exact meaning of the indefinite determiner, which appears in non-referential, indefinite specific, as well as definite non-specific contexts.)

To account for this behavior of a restricted set of nouns, we use what is known in Lexical-Functional Grammar as the mechanism of lexical sharing (Wescoat Reference Wescoat2002, Reference Wescoat, Butt and King2005, Reference Wescoat, Butt and King2007). Lexical sharing describes situations where a single word can “fill in” multiple slots in the phrase structure, for example, where a pronoun is fused with an auxiliary and behaves as a single word yet instantiates both a subject and an auxiliary in the syntactic structure (cf. English he’s or I’ll, which behave in many respects as single words but correspond simultaneously to a subject and an auxiliary in the syntax).

The structures in (13a)–(13b) illustrate the way lexical sharing can be used to account for cases of preposition-determiner contraction in French, where, again, a single preposition can be assumed to instantiate two different syntactic nodes in the structure. This analysis follows Wescoat Reference Wescoat, Butt and King2007, but we omit here the discussion of technical details (see Dalrymple et al. Reference Dalrymple, Lowe and Mycock2019: 114–116, also Bresnan Reference Bresnan, Butt and King1997, Nikitina Reference Nikitina2008 for a related notion of head sharing). In (13a), the preposition and the feminine determiner are separate words, but in (13b), the preposition and the masculine determiner are realized together as a single word.

We believe that the irregular nouns of Kafire are another example of the same phenomenon: they are associated with more than one terminal node in the phrase structure, and project a noun along with its indefinite determiner. In (14b), for example, a single word is lexically associated with information that is normally distributed across two different words, a noun and a determiner (cf. (14a)). Simply put, the noun ‘monitor lizard’ is “shared” by two syntactic nodes in the structure, projecting a class-marked DP rather than a simple NP.

Lexical sharing is only possible when the two syntactic nodes projected by the word are adjacent in the phrase structure. This explains why the determiner is only absent in Kafire when an irregular noun appears at the right edge of the noun phrase. When the same noun is modified by an adjective, and lexical sharing is not possible, the adjective must be followed by an overt determiner, as in (16b). The difference between (16a) and (16b) shows that a restricted set of Kafire nouns are ambiguous: they can behave syntactically as a simple noun or as a combination of a noun and an indefinite determiner.

3.3 Demonstratives and the DP

The last aspect of the noun phrase structure that needs clarifying concerns the position of demonstratives. As we show in this section, the syntactic behavior of demonstratives differs from that of noun class markers, so we treat them as a separate category (Dem). Demonstratives appear in a position external to the noun class marker, and unlike the noun class marker, they can appear before or after the noun phrase.

The ordering difference corresponds to a difference in discourse status, which we cannot explore here in detail. Crucially, in both cases the demonstrative agrees with the class-marked noun phrase (DP) rather than with the head noun. As we saw in (5), when the noun is modified by a class-assigning adjective, the demonstrative – like the determiner – fails to agree with the head noun (18b).

The demonstratives’ adjunct position in our structure corresponds well with coordination facts. In Kafire, only class-marked noun phrases (DPs but not NPs) can be coordinated. Class markers cannot scope over two coordinated NPs, but must be attached to each one of them (19).

Several adjectives can modify the same noun, but they cannot be coordinated (20a)–(20b). The noun that the adjective modifies cannot be omitted even when it is the same for the two coordinated noun phrases (21a)–(21b).

In contrast, when two class-marked noun phrases are coordinated, a demonstrative can be shared by them (each of the coordinates can also have their own demonstrative, but we are interested here in cases where the demonstrative scopes over the coordination, because they provide evidence for the demonstrative’s structural position with respect to the class marker). In (22a)–(22b), the demonstrative scopes over the two class-marked noun phrases, suggesting that it adjoins at a level above the class marker, both when it appears after the noun phrase and when it appears before it, as in (23a)–(23b).

Note that the demonstrative agrees with the coordinate DPs in number, i.e. it appears in the singular when both coordinates are singular, even though semantically, the coordinate structure refers to more than one entity. This effect is formalized for English (cf. ‘this boy and girl’) in King & Dalrymple Reference King and Dalrymple2004, and we assume that the same account would hold for Kafire. We set the technical details aside until further study (along with the issue of the demonstrative’s agreement in class with non-matching coordinates, see Sadler Reference Sadler, Butt and King2003).

4.1 Noun class specification on nouns versus adjectives

One of the crucial observations in this study is the difference between two classes of adjectives with respect to agreement properties. Most adjectives have no effect on the agreement between the determiner and the head noun. Several adjectives, however, impose their own class on the noun phrase that they modify, and that specification overrules the class of the head noun at levels external to the NP.

To account for the behavior of class-assigning adjectives we suggest that the role of noun class information depends on the way that information is encoded in individual lexical entries. On nouns, class specification is optional, so it can be overruled by the value contributed by an adjective (or by semantically motivated class markers, as we discuss in the next subsection). On most adjectives, noun class specification is absent, hence their presence has no effect on agreement. Some adjectives have an inherent class, and their class value can be passed on to the noun phrase.

We now turn to formalizing the intuition about these lexical differences using the tools of Lexical-Functional Grammar (LFG). Because of the surface-oriented nature of the framework, the account does not make reference to a distinction between overt and covert agreement features or directionality of agreement (Haug & Nikitina Reference Haug and Nikitina2016). Because of the framework’s lexicalist nature, differences between nouns and the two types of adjectives can be stated directly on lexical items. We list the class information as an optional value on nouns, as an obligatory value on some adjectives, and as an absence of value on others. The partial LFG-style lexical entries below assign this information to a noun (24), a class-assigning adjective (25) and a regular adjective (26).

Arrows are used in the LFG notation to represent the way that information is shared by nodes in the phrase structure; we explain it in more detail after we introduce the lexical entries. The relevant information in our lexical entries consists of the word’s lexical meaning (represented as the value of the feature pred) and class specification (represented as the value of the feature cl). The technical details of the notation are not relevant for our analysis, the crucial point being that individual nouns and adjectives can contribute, in addition to their lexical meaning, a class feature which can be passed on along the syntactic tree to the noun phrase in which they appear.

The optionality of noun class specification on the noun pɔ̰̄ ‘dog’ is stated directly in (24) (the specification is in parentheses). Noun class specification is absent on the regular adjective wɔ́ ‘black’ in (25), so the presence of that adjective has no effect on the class of the noun phrase. The class value associated with the adjective bī ‘little’ is stated in (26) through what is known in LFG as inside-out function application, which defines constraints on enclosing structures. In our case, the specification on bī ‘little’ attributes a class value (Class 3) to the element of which the adjective is an adjunct (the noun phrase). Simply put, the adjective in (26) can only modify noun phrases of Class 3.

In Lexical-Functional Grammar, information from lexical items is propagated up the syntactic tree and unified at an interpretive level known as f-structure, or functional structure. It is at that level that information coming from different parts of the construction is checked for consistency, so that structures with conflicting or missing information can be ruled out as ill-formed. In the case of adjectival modification, both the head noun and its modifiers may contribute a class value to the f-structure associated with the NP. If the values are different, the obligatory value coming from the adjective will override the optional value coming from the nominal head.

In the partial structure below, the distribution of lexical information between the elements of the interpretive f-structure is defined by functional annotations on phrase structure nodes: $ \uparrow $ = $ \downarrow $ indicates sharing of all information (the node is equivalent in its specification to its mother node), and $ \downarrow $ $ \in $ ( $ \uparrow $ adj) specifies that the daughter node contributes information to the mother node’s substructure (the adjunct). The resulting partial f-structure unifies noun class information coming from the two sources and resolves the potential conflict in favor of the obligatory value (here, Class 3).

Our lexical specification in (26) explains why different class-specifying adjectives can only be used together if they bear the same class value. While adjectives not carrying class information combine freely with other adjectives, adjectives that are inherently specified for class do not normally go well together, unless they are specified for the same class. To sum up, we suggest that both nouns and adjectives can contribute class information to the noun phrase, with which the choice of determiners, demonstratives and anaphoric pronouns must be consistent. Most adjectives are not associated with a particular class, and their presence is irrelevant to agreement. Several adjectives are associated with a particular class, and their presence defines the class of the noun phrase in which they appear; that class might differ from the one normally associated with the head noun. Nouns are associated with specific classes, but their class specification is optional and can be overridden by that of the adjective when the two are in conflict.

We now turn to the last technical component of our analysis: the modeling of agreement with determiners. We need to make sure that the determiner agrees in class with the noun phrase, and in particular, that it must agree with the head noun in the absence of class-assigning adjectives. That is not trivial because we have so far relied on optional specification of class on nouns, making it possible for the NP not to inherit its class value from the head noun. We now need to make sure that this flexibility is only exploited in cases of potential conflict with a class-assigning adjective, and that it does not get abused when the adjectives are not there.

Constraining combinations of nouns with determiners is a challenge for accounts that do not associate nouns with a particular class (such as the Distributive Morphology account suggested in Traoré Reference Traoré2020). In Kafire, nouns show a certain degree of flexibility in the way they combine with class markers, but this flexibility is restricted to combinations with class-assigning adjectives and cases where the class marker contributes its own meaning (such as diminutivity or augmentativity). Apart from these, the choice of the noun class marker is restricted to just one class. Each noun is associated with a particular class, and that class cannot be predicted based on the noun’s meaning (for example, pɔ̰̄ ‘dog’ is Class 1, but dɛ̀ʔɛ̀ ‘hyena’ is Class 2; ná̰ ‘scorpion’ is Class 1, but wɔ̀b ‘snake’ is Class 2; nà̰ ‘man’ is Class 1, but nà̰l $ \underset{\sim }{\acute{\varepsilon}} $ ‘old man’ is Class 3). The associations must be encoded as part of the noun’s lexical entry, even though they can, in certain contexts, be overruled; they are encoded in our model by optional specifications of class on each noun in Kafire.

We define agreement of determiners by what is known in Lexical-Functional Grammar as a constraining equation (Kaplan & Bresnan Reference Kaplan, Bresnan and Bresnan1982). It is a type of constraint that forces a determiner to agree with any value that is already present in the structure, but prevents it from contributing a new value of its own. By adding a constraining equation to the lexical entry of each determiner we ensure that in order for the determiner to be used, the controller NP must bear a specific class value. The value may come from different sources, an adjective or a noun, but it may not be contributed by the determiner alone. Hence, in the absence of a class-specifying adjective, the determiner must agree with the class value inherited by the NP from its head noun, despite the optionality of that noun’s class feature.

The structure in (28) shows how the different agreement mechanisms work together to capture the facts of Kafire agreement. The structure corresponds to the expression ‘this little black dog’, where the head noun is modified by two adjectives. The functional information on the nodes in the structure specifies how the information from the lexical items is integrated into one interpretive f-structure. The demonstrative, the determiner, and the head noun all contribute information to the same f-structure (as indicated by the ( $ \uparrow $ = $ \downarrow $ ) notation), while the adjectives contribute information about the noun’s adjuncts (as indicated by the $ \downarrow $ $ \in $ ( $ \uparrow $ adj) notation in the phrase structure).

The feature structure below the constituent structure illustrates how the class information is unified at the interpretive level of syntactic representation (the f-structure).

One of the adjectives (‘black’) contributes no class information, hence its presence is irrelevant for agreement. The other adjective (‘little’) specifies, through an inside-out function application, the class value of its superstructure, i.e. the class value of the noun phrase within which it appears. Since the class value on the head noun is optional, it is the value contributed by the adjective that gets inherited by the NP and that defines the agreeing value on the determiner. The demonstrative’s value must in turn match the value of the DP it modifies.

4.2 Noun class markers have optional semantic content

We will now turn to the other phenomenon that justifies making the class information optional on nouns: the semantically motivated use of class markers, or the ability of class markers to override the class specification on the corresponding noun phrase in cases where they contribute their own semantic content.

Cross-linguistically, formal agreement classes develop from systems of semantically motivated genders or classifiers (Nicole Reference Nicole1999; Aikhenvald Reference Aikhenvald2000, inter alia). Some of the noun class markers in Kafire still retain traces of their original lexical meaning. This is manifested, most importantly, in a certain degree of flexibility in class assignment. Classes 2 and 3, for example, are associated with the augmentative and the diminutive meanings; they can attach to nouns of other classes, contributing the respective meanings, as in (29)–(30).

Class 4 markers can be used to derive mass nouns from certain count nouns: they contribute the meaning of unbounded quantity, as in (31).

Class 5 markers can be used to refer to abstract qualities associated with categories of humans (32).

The semantic values associated with noun class markers are summarized in Table 6. Note that the augmentative and the diminutive overlap in one aspect of their meaning: both Class 2 and Class 3 markers can be used to encode pejorativity.

To account for the non-agreeing uses, we assume that determiners of Classes 2–5 are not only associated with a formal agreement value but can alternatively contribute semantic values: augment (Class 2), dimin (Class 3), mass (Class 4) and abstr (Class 5). The determiners can either be licensed by a controller noun phrase of the appropriate class or, in cases of a mismatching noun phrase, contribute a semantic value, along with its associated class value. This pattern accords well with the general tendency described by Wechsler (Reference Wechsler2011: 1009) as the Agreement Marking Principle:

We associate the markers of Classes 2–5 with the lexical entries in (33). As previously described, the vowel of the clitic depends on definiteness and, in the case of indefinite markers, on the preceding vowel. Only the semantically motivated use is compatible with noun phrases of a non-matching class.

Table 7 and the specifications in (33) only list the interpretations associated with regular productive uses. Certain nouns can also appear with different determiners depending on their interpretation, but such uses are highly lexicalized and are best treated as instances of ambiguity in the noun’s meaning; for example, the same nouns are used as Class 1 to refer to ethnicity but as Class 4 to refer to the corresponding language (cf. similarity to pairs such as un français (human)–le français (language)). This is different from the way the markers for Classes 2–5 combine with the same count noun to derive the regular interpretations listed in Table 7; the regularity suggests that the interpretations are indeed associated with individual determiners.

Table 7

Semantic values associated with noun class markers in Kafire.

The structures in (35) illustrate the contrast between agreeing and non-agreeing determiner uses. The non-agreeing use produces a semantic effect. Note that the flexibility in class assignment is only possible due to the optionality of the class value in the lexical specification on nouns. The agreeing use is described by a constraining equation, i.e. it presupposes that the determiner combines with an NP with a specific class value. The non-agreeing use, however, is described by a regular equation, predicting that the head noun’s class information can be overruled by the class value contributed by the determiner, which functions in this case as a diminutive, augmentative or an unbounded quantity marker.

Our treatment differs from the treatment adopted in Traoré Reference Traoré2020 for Tagbana, where class markers are assigned additional derivational functions, such as a diminutivizing or a nominalizing function. Our account allows individual class markers to contribute additional meanings, but it does not treat such combinations as new words. The difference between the two accounts can be illustrated by the way they treat nominalization. According to Traoré Reference Traoré2020, class markers can be used in Tagbana to derive nouns from verbs. In our account, nouns in Kafire are zero-derived from verbs and are consistently associated with Class 5 in an action nominalization reading. While the two solutions cover the same set of data, the use of Class 5 markers with action nominalizations is motivated in our account by a historical association of that class with abstract meanings (many abstract nouns referring to processes and states, such as jáá ‘illness’, ɲṵ́nɔ̰̄ ‘sleep’ or ‘knowledge’, are of Class 5 in Kafire, even though they are not derived from verbs).

Our account correctly predicts the way action nominalizations combine with adjectives. In (36), the zero-derived nominalization is modified by an adjective, and the noun phrase is marked as Class 5 because that is the class associated with action nominalizations. If the class marker is assumed to be a derivational suffix it becomes difficult to explain why it attaches to the adjective rather than the verb root. The verb and the adjective would have to be analyzed as a compound, from which a nominalization is derived; this solution seems unmotivated to us, at least in the case of Kafire.

As we already mentioned, our account does not preclude polysemy, i.e. it allows the same noun to be associated with different class markers with different meanings. Some of the zero-derived deverbal nouns can have readings other than that of action nominalization. Such readings are associated with Class 4, but they are highly lexicalized and irregular: they are not available with every verb and they cannot be predicted based on the verb’s meaning (cf. sɔ́ʔɔ́ ‘cook’ – sɔ́ʔɔ̄=r ‘the kitchen’ vs. túgó ‘load’ – túgō=r ‘the load’ vs. kā ‘chew’ – kā=r ‘the meat’). We treat such meanings as a matter of irregular polysemy of the relevant deverbal noun, which has a productive meaning of action nominalization (systematically associated with Class 5) but may also have additional, idiosyncratic meanings (associated, for historical reasons, with Class 4, but not necessarily motivated at the synchronic level).

4.3 Discourse factors in DP-external agreement

Up to now we have focused on the way agreement works at the level below the DP. We conclude with an overview of agreement with anaphoric pronouns.

Pronouns agree in class with their antecedent. Such agreement is regular in all but one respect. Older generations of proficient speakers exhibit a pattern of semantic agreement that is not attested with younger speakers or outside narrative genres (cf. the discussion of morphosyntactic differences between proficient narrative performances and everyday discourse in Nikitina Reference Nikitina2018, based on data from another language spoken in Côte d’Ivoire). Narrative agreement concerns nouns that refer to characters in traditional stories. Instead of agreeing according to the value normally associated with the noun (and manifested in the choice of a determiner), anaphoric pronouns refer to such characters in Class 1, i.e. the class historically associated with humans.

This pattern of narrative agreement is illustrated in a pair of sentences extracted from a text in our corpus (37)–(38). In (37), ‘hyena’ combines with a Class 2 determiner, as expected, but a Class 1 emphatic pronoun is used to refer to Hyena (the emphatic pronoun is used here in a logophoric function, to signal reference to the reported speaker; Silué In prep.a). In (38), a Class 1 anaphoric pronoun is used again to refer to Hyena as a character in the story.

The phenomenon of narrative agreement is different from the semantically motivated use of determiners discussed in the previous subsection. In (37), the noun combines with its regular Class 2 marker, and the irregularity is only manifested in the choice of anaphoric pronoun. We explain this use as an instance of personification, characteristic of cases where a noun phrase refers to a character, naming a highly agentive, unique (in the context of a particular story) and human-like participant.

Narrative agreement is only attested with highly volitional acting characters; in contexts where no volitionality is involved the same entity agrees in its regular class. In (39), from the same story, a Class 2 anaphoric pronoun is used to refer to Hyena, in a way consistent with the determiner choice. The absence of personification is explained by the fact that the pronoun refers to the character in a rather passive role: Hyena is treated here as an object rather than a volitional agent. Such examples suggest that narrative uses of Class 1 anaphors are licensed by situational animacy, i.e. they are highly dependent on the discourse context.

Unlike determiners and demonstratives, which agree based on the formal noun class value, anaphoric pronouns of Class 1 are sensitive to a mismatch between the formal value and the semantic content. They can be described as looking for a highly human antecedent, regardless of its noun class value.

We can capture the effect of personification by essentially the same method as the one we used to license semantically-motivated uses of determiners, but this time polysemy characterizes pronouns rather than determiners. We associate pronouns of Class 1 with two different lexical entries. One simply specifies that the antecedent is of Class 1; the other specifies that the antecedent is human. The latter lexical entry is only attested in older speakers who retain the archaic discourse-motivated use. We leave out the technical details but refer the reader to the literature on pronominal binding where restrictions on antecedents are modeled within the Lexical-Functional Grammar framework (Dalrymple Reference Dalrymple1993, Dalrymple et al. Reference Dalrymple, Lowe and Mycock2019).
