Lexical Phrases: An Essential Brain-Adaptive Requisite for Second Language Acquisition

Abstract

In the incessant attempts to overcome second language (L2) acquisition difficulties and to improve second language proficiency, most of the proposed methodological approaches which address this issue place high value on individual vocabulary and grammar of a second language and fall short of integrating lexical phrases/multi-unit expressions into the teaching approaches. This, if does not exacerbate acquisition difficulties, does not by any means improve it. On this view, the ubiquitous interest in lexical phrases gave rise to their investigation in language acquisition. This paper reviews the importance of lexical phrases in language acquisition by providing further insight into their peripheral role in first language and second language acquisition alike. Also, Evidence from neurolinguistic and psycholinguistic studies are provided to account for lexical phrases representation and brain-adaptability. Further, this paper suggests the implementation of lexical phrases, in general, and the Lexical Approach, in particular, in second language acquisition. Finally, further pedagogical implications as well as self-paced ones are proposed.
