A phrasal verb is a verb that is made up of a main verb together with an adverb or a preposition or both.
Typically, their meaning is not obvious from the meanings of the individual words themselves.

For example:

• She has always looked down on me.

The phrasal verb 'to look down on someone' doesn't mean that you are looking down from a higher place at someone who is below you; it means that you think that you are better than someone.

Phrasal Verb Form: VERB + ADVERB

These phrasal verbs can be:
transitive (direct object)
intransitive (no direct object)


transitive

put off = postpone
turn down = refuse
For example:

• We will have to put off the meeting.
• They turned down my offer.

intransitive

get up = rise from bed
break down = stop working
For example:

• I don't like to get up.
• He was late because his car broke down.

Phrasal Verb Form: VERB + PREPOSITION

All prepositional verbs have direct objects (they are transitive).

believe in = have faith in the existence of
look after = take care of
talk about = discuss
wait for = await

For example:

• I believe in destiny.
• He is looking after the cat.
• Did you talk about this?
• Jerry is waiting for Mary.

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"

Phrasal Verb Form: VERB + ADVERB + PREPOSITION

get on with = have a friendly relationship with
put up with = tolerate
look forward to = anticipate with pleasure
run out of = use up, exhaust

For example:

• He doesn't get on with trainer.
• I won't put up with your lifestyle.
• I look forward to seeing you.
• We have run out of eggs.
