Morphosyntax Constructions of the World's Languages

The skeletal structure of a sentence is defined by the propositional acts of reference, predication, and modification. Reference is carried out by a referring phrase. The prototypical head of a referring phrase denotes an object; this is a noun. Modifiers are dependents of a noun that form attributive phrases. The prototypical head of an attributive phrase denotes a property; this is an adjective. A clause predicates something of a referent or referents. The prototypical head of a clause denotes an action; this is a verb. Reference, modification, and predication of nonprototypical concepts is possible, and often expressed by distinct constructions. Three principles govern how combinations of information packaging and semantic content are expressed: any concept can be packaged in any way; some ways are more ‘natural’ than others; and how they are packaged is constrained by conventions of the speech community. Nonprototypical constructions often share properties of ‘neighboring’ prototypical constructions. They often differ by having additional forms coding the nonprototypical function, and/or by a lesser potential for expressing associated grammatical categories (e.g., inflections).
