Sound Like a Native

Collocations are two or more words that usually go together and sound more natural to native speakers.  For instance, instead of saying “have a break” native speakers would say “take a break.”  Instead of saying “make a crime” native speakers would say “commit a crime.”  Instead of saying “wash the dishes” native speakers would say “do the dishes.”  It’s not necessarily that the other sentences are wrong, it’s just not how native English speakers talk.
