What is the definition of "collocation"?

The correct definition of "collocation" is a combination of words that frequently occur together. This concept is essential in understanding how language works, as certain words often pair with others to create natural-sounding phrases. For instance, we commonly say "make a decision" instead of "do a decision." Such combinations are not arbitrary; they reflect common usage patterns in a language. Recognizing collocations can significantly improve fluency and comprehension, as it helps learners or speakers to use language in a way that feels authentic to native speakers. This understanding aids in producing more coherent and contextually appropriate sentences.
