This article presents two questionnaire experiments that investigate the processing complexity of a variety of nested constructions in Japanese. The first experiment demonstrated that embedded structures containing a direct object NP in the most embedded clause were more complex than comparable nested structures that lacked an object NP in the most embedded clause. The second experiment demonstrated that a construction consisting of a relative clause embedded within a sentential complement is less complex than the reverse embedding, consisting of sentential complement embedded within a relative clause. These results are discussed in terms of the syntactic prediction locality theory (Gibson 1998).

Many Mayan languages use a special verb form, the agent focus form, when extracting the subject of a transitive clause. These verbs have a cluster of properties that have resisted satisfactory analysis. This article suggests that in Tzotzil, agent focus verbs are inverse, in the sense of Algonquian linguistics, and that their distribution is determined by the relative obviation status of agent and patient. Evidence for the analysis comes from syntactic constraints on agent focus verbs and on their use in discourse. The properties of these verbs provide further evidence that obviation can play a central role in languages where it is not a morphological category.

The comparison of the moribund dialects of Ocracoke Island, North Carolina, and Smith Island, Maryland, demonstrates that valuable insight into the patterning of variation and change in language death can be obtained by investigating moribund varieties of healthy languages. In addition, it is crucial to investigate not only cases of death by linguistic decay (dissipation), but also cases of death by population attrition in which linguistic distinctiveness is maintained or heightened among fewer speakers (concentration). The comparative investigation of both types of language death lends insight into the macrolevel socioeconomic and microlevel sociopsychological factors that lead to the maintenance or demise of moribund languages and language varieties, as well as the nature of change in language death. It is demonstrated that change in both concentrating and dissipating varieties is rapid but otherwise indistinct from change in healthy varieties and that unusual patterns of variation and change can be explained by appealing to the social significance of language features.

It is a truism that people speak 'loosely'—that is, that they often say things that we can recognize not to be true, but which come close enough to the truth for practical purposes. Certain expressions, such as those including exactly, all and perfectly, appear to serve as signals of the intended degree of approximation to the truth. This article presents a novel formalism for representing the notion of approximation to the truth, and analyzes the meanings of these expressions in terms of this formalism. Pragmatic looseness of this kind should be distinguished from authentic truth-conditional vagueness.

This report describes the unique behavior of two clitic particles in a moribund Amazonian language. In Chamicuro na and ka are basically definite articles, yet they contrast for tense (ka indicates a past action while na is used in present and future contexts). The prosodic eneliticization of na and ka is completely predictable from general phonological constraints alone and thus does not depend on any syntactic factors. Consequently, the stranding of an article in a different clause from its head noun follows automatically from the posited constraint system without any need to stipulate additional formal devices.
