A phrasal verb is a verb that is made up of a main verb combined with an adverb or a preposition, or both. Sometimes the meaning is really obvious but more often than not the meaning cannot be guessed by looking at the individual words. For example, look up can mean ‘look in an upward direction’ whereas give up means to ‘stop trying to do something’.
