WHAT IS PHRASAL VERB?

A phrasal verb is a verb followed by a preposition or an adverb; the combination creates a
meaning different from the original verb alone. Example :   To get  =  to obtain I need to get a new battery for my camera. To get together  =  to meet  Why don’t we all get together for lunch one day?

Phrasal verbs are part of a large group of verbs called “multi-part” or "multi-word” verbs.
The preposition or adverb that follows the verb is sometimes called a particle.
