Multiword verbs consist of a verb and one or two particles or prepositions. There are three types: phrasal verbs which are verb+adverb, prepositional verbs which are verb+preposition, and phrasal-prepositional verbs which are verb+adverb+preposition. Phrasal verbs can be transitive or intransitive and separable phrasal verbs allow separation of the verb and particle when used with a direct object but not with pronouns. Prepositional and phrasal-prepositional verbs are always used with a direct object and cannot be separated.

2. Definition
Are 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.

3. Structure: verb+adverb
Phrasal verbs can be:

Transitive (direct object)

Intransitive (no direct object)
phrasal verbs

4. Separable phrasal verbs
When phrasal verbs are transitive (that is, they have a direct
object), we can usually separate the two parts. For example,
"turn down" is a separable phrasal verb. We can say: "turn
down my offer" or "turn my offer down". Look at these example
sentences:

They turned down my offer.

They turned my offer down.

5. Separable phrasal verbs
However, if the direct object is a pronoun, we have no choice.
We must separate the phrasal verb and insert the pronoun
between the two parts. Look at these examples with the
separable phrasal verb "switch on". Note that the last one is
impossible:

John switched on the radio.

John switched the radio on.

John switched it on.

7. Prepositional Verbs
structure: verb + preposition
Because a preposition always has an
object, all prepositional verbs have
direct objects.

8. Example
Prepositional verbs cannot be separated. That means that we
cannot put the direct object between the two parts. For
example, we must say "look after the baby". We cannot say
"look the baby after":
Who is looking after the baby?
Who is looking the baby after?Incorrect

10. Phrasal-prepositional Verbs
Structure: verb + adverb+
preposition
phrasal-prepositional verbs end with a
preposition, there is always a direct
object. And, like prepositional verbs,
phrasal-prepositional verbs cannot be
separated. Look at these examples:

We ran out of gas.

We ran out of it.
