The lexical approach is a method for teaching foreign languages developed by Michael Lewis in 1993. It is based on the idea that understanding words and phrases is key to language learning. The principles of this approach include that language consists of lexicalized grammar and grammaticalized lexis, vocabulary and grammar are integrated, and collocations are an organizing principle. Examples of lexical items taught include words, phrases, collocations, and sentence frames. Teaching lexical chunks brings fluency and they can be acquired as wholes since they are context-bound.
