I argue that the variation within and across contexts detailed by Shin & Miller is indicative of a broader phenomenon in which morphosyntax and the discourse context are intertwined, including elements like perspective, discourse relations, information structure, and common ground. Appealing to independent evidence highlighting the role of…

The well-known sampling limitation of most longitudinal corpus data can be even more consequential in the study of morphosyntactic variation in child language. An analysis of caregiver input suggests that variable use in overlapping contexts may be hard to find by solely relying on corpus data collected under the sampling procedures that are…

This article presents a developmental pathway for the acquisition of morphosyntactic variation. Although there is abundant evidence that morphosyntactic variation is pervasive among adults, much less is known about how children acquire such variation. The literature thus far indicates that the pathway of development involves first producing only…

When acquiring the English plural, children correctly produce plural words long before they develop an understanding of morphological structure. When acquiring Sesotho noun prefixes, children are aware of the multiple constraints governing variation from a young age. Both of these cases raise questions about the Shin and Miller (2022) account of…

This article examines whether children alter a variable phonological pattern in an artificial language towards a phonetically-natural form. We address acquisition of a variable rounding harmony pattern through the use of two artificial languages; one with dominant harmony pattern, and another with dominant non-harmony pattern. Overall, children…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

Constraints on linguistic variation are consistent across adult speakers, yielding probabilistic and systematic patterns. Yet, little is known about the development of such patterns during childhood. This study investigates Spanish subject pronoun expression in naturalistic data from 154 monolingual children in Mexico, divided into four age…

Faroese is at the tail end of a change from an Icelandic-type syntax in which V-to-T is obligatory to a Danish-type system in which this movement is impossible. While the older word order is very rarely produced by adult Faroese speakers, there is evidence that this order is still marginally present in the adult grammar and thus only dispreferred,…

The role of homophony in language change and in child morphological acquisition has often been made recourse to. Regarding the former it has been proposed that the threat of homophony can prevent a sound change from going to completion. With respect to the latter, it has been vaguely and contradictorily claimed that homophonous morphological…

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…

A study of the acquisition of interrogative forms in children of high socioeconomic status reveals that utterances belong more to the colloquial than to the standard range. It is concluded that disadvantaged children would show similar usage, leading to the suggestion that teachers teach language as they use it. (Text is in French.) (CDSH/CLK)

Various commentaries are included in response to an article on filler syllables and their status in emerging grammar. (Author/VWL)

This paper examines aspects of variation in child language, and specifically how children express causal relations in complex sentences. Four particular types of variation were observed: (1) the order of clauses and the connectives used to link clauses; (2) mothers' causal statements; (3) interaction of language form and content, in the form of…

Because of the syntactic differences between Spanish and Quechua, Quechua-speaking children must make major word order adjustments to learn the Peruvian Spanish taught in school. This study investigates whether the order or time sequence in which these changes are adopted reflects any general constraint, or is in any way predicted by a theory of…

This paper attempts to show the relationship between variable rules and more widely used psycholinguistic constructs such as amalgams and schemas, and to point out how variationists' methods can be useful in the study of language acquisition. The traditional rule, the rule for forming the past tense of regular verbs in English, is discussed as it…
