change

If you change something, you make it different than before.

Example: Ellen changed the sentence so that it was correct.

A change is when something becomes different.

Example: The building plan required some small changes.

When you get change for a bill, you get smaller bills or coins that equal the amount of the original bill. For example, if you get change for a $5 bill, you may get five $1 bills or you may get four $1 bills and coins that add up to $1 or you may get some other combination of bills and coins.

Example: Can I get change for this $100 bill please?

A change is a replacement.

Example: I brought a change of clothes, just in case.
