What are Phrasal Verbs?

Phrasal verb is the name given to an English verb which is composed of two or three words. One verb is combined with a preposition (like on, in, under) or an adverb (like up, down, away). Sometimes a phrasal verb can have a meaning that is very different to the meaning of at least one of those two or three words separately. Some text books call these verbs multi-word verbs. Phrasal verbs are used more frequently in everyday speech than in formal, official writing or speaking.

Here are some examples:
