Origins of Complex Syntax in Interlanguage Development

This study examines the emergence of complex syntax in interlanguage (IL) development through a functionalist analysis of longitudinal, conversational IL data from two Vietnamese learners of English. The study focuses on discourse-pragmatic factors in the learners′ production and acquisition of complex syntax, specifically on their reliance on collaboration by interlocutors in the production of complex syntactic structures. Its findings offer a test of the utility of Givón's functionalist approach in SLA studies, and of claims by Hatch and others to the effect that “syntax develops out of conversation.” The interdependence of different linguistic levels in IL development is demonstrated, and the use of a variety of analytical units is shown to be critical in characterizing prepositional encoding in IL speech.
