Phrasal verb

Phrasal verb is the name given to an English verb which is composed of two or three words. One verb is combined with a preposition (like on, in, under) or an adverb (like up, down, away). Sometimes a phrasal verb can have a meaning that is very different from the meaning of at least one of those two or three words separately. Some textbooks call these verbs multi-word verbs. Phrasal verbs are used more frequently in everyday speech than in formal, official writing or speaking. 

Here are some examples:

Maria didn't know the word, so she looked it up in the dictionary.

Oh no, we've run out of milk! I'll have to buy some more.

Farmers have to get up early in the morning.

The rocket took off with a loud roar.

Often these phrasal verbs have a one-word equivalent in other languages. 
In Spanish, to get up can be translated as levantarse, in French as se lever etc.

 Types of phrasal verbs 
There are four different types of phrasal verbs.
These are:
 Phrasal verbs which take objects and are separable 
 Phrasal verbs which take objects and are inseparable
 Phrasal verbs which do not take objects  (these are always inseparable) 
 Three-word phrasal verbs

Instead of "separate" or "separable", some text books use the word "split" or "splittable".

A useful piece of advice to confused students of English is this:

If you do not know if a phrasal verb is separable or inseparable ALWAYS use a noun or noun phrase and do not try to separate the verb.
