compression

Whenever something is squished together, compression takes place, like a tight bandage around your sprained ankle — the compression helps protect it from further injury.

Compression comes from the Latin word compressare, meaning “to press together.” Compression is an important part of how car engines function: fuel and air are compressed then ignited and that makes the power that turns the wheels. Compression can also happen to your day's schedule, such as when a snow storm causes school to start late, a schedule compression means that you have all your classes but they are shorter.
