Phrasal Verbs are idiomatic expressions, combining verbs and prepositions to make new verbs whose meaning is often not obvious from the dictionary definitions of the individual words. They are widely used in both written and spoken English, and new ones are formed all the time as they are a flexible way of creating new terms.
