* A phrasal verb is a combination of a verb and an adverb or preposition.
* The usual meaning of the verb is normally altered.
* Phrasal verbs are used in four main structures.
1 Phrasal verbs are verbs that combine with adverbs or prepositions. The adverbs and prepositions are called particles, for example `down’, `in’, `off’, `out’, and `up’.

Mr Knight offered to put him up.
2 Phrasal verbs extend the usual meaning of the verb or create a new meaning. For example, if you `break’ something, you damage it, but if you `break out of’ a place, you escape from it.

The pain gradually wore off.
3 Phrasal verbs are normally used in one of four main structures. In the first structure, the verb is followed by a particle, and there is no object.
