Lexical phrases have been shown to have a positive effect on learners’ language proficiency, learners’ expertise in writing in the target language, as well as on learners’ capacity to communicate by means of the target language. The use of lexical phrases is also related to oral fluency, particularly at the beginning of second language acquisition. Lexical phrases may be treated as wholes, either as complete or partially preassemble units. As such, they are stored in the lexicon as unanalyzed chunks just like words. Being ready-made, they are easily retrieved. Consequently, they offer learners the possibility of expressing themselves in the absence of rich linguistic resources.
