A phrasal verb is a verb followed by a preposition or an adverb; the combination creates a meaning different from the original verb alone.
There are hundreds of PHRASAL VERBS in English and it is often impossible to guess the meaning even though you may understand the separate parts that make up each verb. On top of that many phrasal verbs have more than one meaning !!!
Example : (with and without a preposition)
To get = to obtain
I need to get a new battery for my camera.
To get away = to escape
The prisoners tried to get away last night.
Example : (with more than one meaning)
To make up :
To assemble or put together
To be reconciled
To put cosmetics
Phrasal verbs are part of a large group of verbs called “multi-part” or "multi-word” verbs.
The preposition or adverb that follows the verb is sometimes called a particle. Phrasal verbs and other multi-word verbs are an important part of the English language. However, they are mainly used in spoken English and informal texts. They should be avoided in academic writing where it is preferable to use a formal verb such as “to postpone”rather than “to put off”.
Some phrasal verbs are transitive. (A transitive verb always has an object.)
Example : I made up an excuse. ('Excuse' is the object of the verb.)
Some phrasal verbs are intransitive. (An intransitive verb does not have an object.)
Example : My car broke down.
Some transitive phrasal verbs are separable. (The object is between the verb and the preposition.)
Example : I always take my shoes off when I come home.
Some transitive phrasal verbs are inseparable. (The object is placed after the preposition.)
Example : I will look into the matter as soon as possible.
Some transitive phrasal verbs can take an object in both places.
Example : I picked up the paper. / I picked the paper up.
However, if the object is a pronoun, it must be placed between the verb and the preposition.
Example : I picked it up.
