'Can I put--I want a slippers to put on': young children's development of request forms in a code-switching environment.

This paper concerns the development of semi-modal want/want to, and modals may, can and could in two Trinidadian children, whose Verb Phrase development was studied in naturalistic settings, between the ages of 2;3 and 4;1, and 2;4 and 4;9. The similarities and differences in development between the two are important for underlining a number of key factors in the acquisition process. Accepting the salience of requests/demands in early child language, the study draws attention to the child's propensity for using the means most readily available to him/her in the input, for expression of this function. Additionally, there is evidence of the child's ability to make stylistic discriminations at a very early age and of the propensity for making semantic distinctions among forms. The study indicates that work on the development of grammatical features is incomplete without consideration of sociolinguistic aspects of usage as integral to grammatical acquisition from the outset.

The early development of perfect aspect: adverbial, verbal and contextual specification.

In a longitudinal study concerned to assess Verb Phrase (VP) development in three Trinidadian children, adverbials were found to be crucial in delineating specific areas of semantic intent, and to develop early (between ages 2; 3 and 3; 0). The children were studied over a two-year period, from the onset of morphological marking on the verb, and were recorded two to four hours per month, in their home environments, with a variety of addressees. Two of the children were exposed to, and acquired, both TC and SE verb categories and the third, TC, but the existence of TC past-completive zero phi as a prominent verbal marker in all their systems made for reliance on adverbial and extralinguistic context in delineating meaning intentions at an early stage; the use which they made of adverbial specification, in particular for marking perfect aspect, indicates how useful these elements may be for precise specification of the development of tense-aspect categories. When they are considered alongside other VP features a clearer overall assessment of tense-aspect development may be made.
