While affix ordering often reflects general syntactic or semantic principles, it can also be arbitrary or variable. This article develops a theory of morpheme ordering based on local morphotactic restrictions encoded as weighted bigram constraints. I examine the formal properties of morphotactic systems, including arbitrariness, nontransitivity,…

Noun-class prefixes are obligatory in most Bantu languages. However, the Sotho languages (Sesotho, Setswana, Sepedi) permit a subset of prefixes to be realized as null at the intersection of "unmarked" phonological, syntactic, and discourse conditions. This raises the question of how and when the licensing of null prefixes is learned. Using…

What is the mechanism by which a linguistic change advances across successive generations of speakers? We explore this question by using the model of incrementation provided in Labov 2001 and analyzing six current changes in English. Extending Labov's focus on recent and vigorous phonological changes, we target ongoing morphosyntactic(-semantic)…

Provides evidence from child language acquisition and comparative syntax for existence of a syntactic parameter in the classical sense of Chomsky (1981), with simultaneous effects on syntactic argument structure. Implications are that syntax is subject to points of substantive parametric variation as envisioned in Chomsky, and the time course of…

Discusses recent research that has examined the early stages of language development in signed and spoken languages as well as suggestions that there is an advantage for the acquisition of signed languages. Specific attention is focused on whether or not a single timing mechanism underlies early milestones in the acquisition of both vocabulary and…

Presents the Lexical/Semantic Hypothesis, which proposes that early learning is more lexically oriented, and that early word combinations can be explained by more semantically oriented accounts than the Full Competence Hypothesis. The article also replaces the Grammatical Infinitive Hypothesis with the Modal Hypothesis. (32 references) (Author/CK)

Research on which portions of this study are based was performed under a National Science Foundation Grant and a grant from the National Endowment for the Humanities. (VM)

The monograph under review is a study of the acquisition of certain complex linguistic structures by children over the age of five. After a short introduction, Chomsky describes in chapter 2 the linguistic properties of four types of constructions: (1) John is eager to see; John is easy to see; (2) John promised Bill to shovel the driveway; John…

This paper reviews research findings on the structural properties of deaf childrens' gestural communication systems and evaluates those properties in the context of data gained from other approaches to the question of the young child's language-making capacity. (over 100 references) (JL)
