The lexical approach is a way of analysing and teaching language based on the idea that it is made up of lexical units rather than grammatical structures. The units are words, chunks formed by collocations, and fixed phrases.
Example:
The phrase 'Rescue attempts are being hampered by bad weather' is a chunk of language, and almost a fixed phrase. It is formed by the collocations 'Rescue' + 'attempt', 'rescue attempt' + 'hampered', 'hampered' + 'by', 'hampered by' + 'bad weather'.
