Two part verbs
Some verbs consist of two words – a verb and a particle (p). These verbs have a number of patterns:
Peter came in. (N + V + p)
He took out his diary. (N + V + p + N)
He gave the money back. (N + V + N + p)
Some transitive two part verbs are phrasal verbs. They have two different patterns.
N + V + N + p
She gave the money back
He knocked the vase over
We will be leaving our friends behind
N + V + p + N
She gave back the money
He knocked over the vase
We will be leaving behind our friends.
When the object is a pronoun these verbs always have the first pattern N + V +N + p:
She gave it back
He knocked it over
We will be leaving them behind
Three part verbs
Some verbs are made up of three parts – a verb and two particles. They have the pattern:
N + V + p + p + N:
His girl friend walked out on him.
She soon caught up with the other runners
Children should look up to their parents.
