What does the concept of 'lexical chunks' refer to in language learning?

The concept of 'lexical chunks' refers to groups of words that are used together frequently in a language. This concept is important in language learning because it emphasizes how native speakers often communicate using fixed or semi-fixed expressions rather than relying solely on individual words. These chunks can include phrases, collocations, idioms, or even entire sentences that commonly occur together in natural speech or writing.

Recognizing and using these chunks helps learners speak and write more fluently and naturally, as they can recall familiar patterns rather than constructing sentences from scratch with single words. For example, phrases like "kick the bucket" or "make a decision" are considered lexical chunks because they are commonly used together and carry meanings that might not be obvious from their individual components. Understanding and incorporating these chunks into language practice can significantly enhance overall communicative competence.
