In the English lexicon, laryngeal alternations in the plural (e.g. "leaf" ~ "leaves") impact monosyllables more than finally stressed polysyllables. This is the opposite of what happens typologically, and would thereby run contrary to the predictions of "initial-syllable faithfulness." Despite the lexical pattern, in a wug test we found…

In this article we offer up a particular linguistic phenomenon, quantifier-variable binding in Kannada ditransitives, as a proving ground upon which competing claims about learnability can be evaluated with respect to the relative abstractness of children's grammatical knowledge. We first identify one aspect of syntactic representation that…

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,…

Phonological constraints can, in principle, be classified according to whether they are natural (founded in principles of universal grammar (UG)) or unnatural (arbitrary, learned inductively from the language data). Recent work has used this distinction as the basis for arguments about the role of UG in learning. Some languages have phonological…

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)…

Examined the development of principles of control in the grammar of 15 preschool children over a 9-month period, focusing on pronominal reference. The results confirm a developmental sequence that is driven by lexical learning and changing structural analyses. (38 references) (MDM)

An account of grammatical acquisition is developed within the parameter setting framework applied to a generalized categorical grammar (GCG). Computational simulation shows that several resulting acquisition procedures are effective on a parameter set expressing major typological distinctions based on constituent order, and defining 70 distinct…

Offers an explanation for the gap in the paradigm of the verb "be" where amn't is expected to be found. The explanation is base on a combination of multiple-default inheritance and function-based morphology, as embodied in word grammar. (Author/VWL)

This study presents evidence for the psychological reality of the Subset Principle as a determinant of the acquisition of Governing Category Parameter settings for English anaphors and pronominals. Prelingual deafness was used as a natural experiment in the acquisition of English in the presence of variably impaired access to English language…

Examines the acquisition of tense-aspect morphology in children acquiring English. The article found that children start using past inflections with achievement verbs and progressive inflections with activity verbs. Results indicate that early development of tense-aspect morphology is influenced by the inherent aspect of the verbs. (56 references)…
