Phrasal Verb

A phrasal verb is a verb followed by a preposition or an adverb; the combination 

creates a meaning different from the original verb alone.

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 intrasitive . (An intransitive verb does not have an object.)

Example : My car broke down.

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 : 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 book.

   I picked the book up.
