The lexical approach is a method of analyzing and teaching language that focuses on lexical units such as words, phrases, and collocations, rather than grammatical structures. It was introduced by Michael Lewis in 1993, who argued that language consists more of grammaticalized lexical items than lexicalized grammar. A key concept is that learning a language involves understanding and producing lexical phrases as chunks. Instruction in the lexical approach emphasizes fixed expressions that are commonly used, rather than unique phrases and sentences. It aims to teach students frequently used phrases rather than lists of isolated vocabulary words.
