Theory:

English has several different kinds of verbs, one of which is called Multi-word verbs.

A Multi-word verb is a verbs which consist of a verb and one or two particles or prepositions (e.g. up, over, in, down).

There are three types of multi-word verbs:

phrasal verbs.

prepositional verbs.

phrasal-prepositional verbs.

If the verb preposition combination has a different meaning from the verb used, then it is called a Phrasal verb:

Look up at the stars. - physically look up, same as look  (not a phrasal verb)

look up a word. - research something (phrasal verb)

Phrasal verbs have two parts: a main verb and an adverb particle.

The most common adverb particles used to form phrasal verbs are around, at, away, down, in, off, on, out, over, round, up:

Phrasal verbs are often, but not always, less formal than a single word with the same meaning.

Another kind of multi word verb is a prepositional verb, which has two parts: a verb and a preposition which cannot be separated from each other:

There are some differences between Phrasal verbs and prepositional verbs. We have looked at how the meaning changes, but there is another one.

With phrasal verbs the object can come before or after the particle if the object is not a pronoun.

He looked up the word.

He looked the word up.

With prepositional verbs, the object is always immediately after the preposition.

He looked up at the sky. - correct

He looked at the sky up. - not correct

Some Phrasal-prepositional verbs have three parts: a verb, a particle and a preposition. The particle and the preposition cannot be separated.

With such verbs, the object always comes immediately after the preposition, and not in any other position:

He looked up to his boss. - He respected his boss.
