A collocation is a combination of words that are commonly used together; the simplest way of describing collocations is to say that they ‘just sound right’ to native English speakers.

Collocations include noun phrases like ‘ stiff wind’ and 'weapons of mass destruction’, phrasal verbs such as 'to get together’ and other stock phrases such as 'the rich and famous’
