A phrasal verb is a verb followed by a preposition or an adverb; the combination creates a meaning different from the original verb alone.
To get = to obtain
I need to get a network connection for my computer.
To get together = to meet
There is a get together for lunch on the occasion of Annual Day.
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.
1. Transitive and intransitive phrasal verbs :
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.
2. Separable or inseparable phrasal verbs :
Some transitive phrasal verbs are separable. (The object is between the verb and the preposition.
Example : I looked the word up in the dictionary.
Some transitive phrasal verbs are inseparable. (The object is placed after the preposition.)
Example : The supervisor will look into the case as soon as possible.
Some transitive phrasal verbs can take an object in both places.
Example : I picked up the newspaper.
I picked the newspaper up.
However, if the object is a pronoun, it must be placed between the verb and the preposition.
Example : I picked it up.
