A phrasal verb is a verb that has two or more words.
They are basically made of a verb and a particle.
For example:
Turn up means increase volume: Turn up the radio, I love this song!
Call off means cancel: They called off the football game because of the bad weather.
Take back means return: I need to take back these books to the library.
Changing the participle used with a verb totally changes its meaning.
Keep on means continue: He kept on working after everyone else went home.
Keep out means prevent from entering: Please keep out of my bedroom.
Keep up means stay on schedule: I found it hard to keep up with my friends when we all went jogging.
Some phrasal verbs may be split i.e. the object of the sentence can come after the phrasal verbs or in-between the two parts. This does not change its meaning.
I gave away some old books to a charity store.
I gave some old books away to a charity store.
Other phrasal verbs cannot be split. For example: My alarm goes off at 6am, is correct, but, My goes alarm off at 6am, is not.
