The lexical approach focuses on teaching vocabulary through word chunks or combinations rather than isolated words. It views language as being grammaticalized lexis rather than lexicalized grammar. Examples of key principles are that learners should be exposed to vocabulary in context to understand usage, and lexical syllabi should be used to determine which lexical items to teach based on frequency and usefulness. Practice activities develop automatic recognition of lexical phrases to aid fluency. The lexical approach emphasizes vocabulary learning over grammatical rules.
