If you chop something, you cut it into pieces with strong downward movements of a knife or an axe.

A chop is a small piece of meat cut from the ribs of a sheep or pig.

When people chop and change, they keep changing their minds about what to do or how to act.

If something is for the chop or is going to get the chop, it is going to be stopped or closed. If someone is for the chop, they are going to lose their job or position.
