A phrasal verb is a group of words (a verb plus a preposition or a verb plus an adverb) that, when combined, have a different meaning than the original verb.
Take, for example, the phrasal verb ‘put off’. It means to postpone, which is not the same as the meaning of the two words together, ‘put’ and ‘off.’.
Another example would be the phrasal verb’ turn down’, which means to refuse.
