The present study examined the production of inalienable possession with body parts in Spanish among 20 school-age children of Mexican-born parents born and raised in the United States. The results were compared to those of 20 first-generation immigrant parents (main input providers), 27 Spanish-dominant children of similar age, and 12 Spanish…

In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

This article reviews prominent research on non-English-speaking children's extramural acquisition of English through digital media, and examines the understudied scenario of possible effects of such second language (L2) English input on domestically dominant but globally small first languages (L1s), with Icelandic as the test case. We outline the…

In this study, verb placement with respect to negation is investigated in elicited production and elicited sentence imitation data collected with child second language (L2) learners of German. These data are compared to published data from adult L2 learners, which were collected with the same elicitation materials and were re-analysed for the…

We study the learnability problem concerning the dative alternations in English (Baker, 1979; Pinker, 1989). We consider how first language learners productively apply the double-object and to-dative constructions ("give the book to library"/"give the library the book"), while excluding negative exceptions ("donate the…

Amaral & Roeper's Multiple Grammars (MG) proposal offers an appealingly simple way of thinking about the linguistic representations of bilingual speakers. This article presents a commentary on the MG language acquisition theory proposed by Luiz Amaral and Tom Roeper in this issue, focusing on the theory's implications for child…

The central claim in Amaral and Roeper's (this issue; henceforth A&R) keynote article is that everyone is multilingual, whether they speak one or more languages. In a nutshell, the idea is that each speaker has multiple grammars or "sub-sets of rules (or sub-grammars) that co-exist". Thus, rather than positing complex rules to…

This study investigates how derivational complexity interacts with first language (L1) properties, second language (L2) input, age of first exposure to the target language, and length of exposure in child L2 acquisition. We compared elicited production of "wh"-questions in French in two groups of 15 participants each, one with L1 English…

The present study examines and compares the extent to which advanced L2 learners of Spanish and Spanish heritage speakers acquire the syntactic and semantic properties that regulate the grammatical representation of double complementizer questions in Spanish, a CP-related structure not present in English. Results from an aural sentence completion…

Haznedar (2007) argues that longitudinal data from a child learner of English who has Turkish as a first language (L1) constitute a counterexample to the Aspect Hypothesis. In this commentary, we show that her argument is not warranted because the Aspect Hypothesis does not presuppose that tense is defective, contra her claim. However, Haznedar's…
