The word break has several common meanings:

1. To damage something so badly that it stops working or falls apart. When you break a glass, it shatters into pieces. When your bike chain breaks, you can't ride until it's fixed. Sometimes things break suddenly with a snap or crash, and sometimes they break gradually, like a rope that frays until it finally gives way.
2. To interrupt or stop something. You take a break from homework to rest your brain. Schools have spring break when classes pause for a week. A break in a conversation happens when someone stops talking. When day breaks, darkness gives way to morning light.
3. To go against a rule or promise. Someone who breaks a law faces consequences. If you break your word, you fail to do what you promised. Breaking rules is different from bending them: when you break a rule, you clearly violate it.
4. In sports or games, a lucky break is a fortunate opportunity, like when a defender makes a mistake that helps the other team score. A big break means a sudden chance for success, like an actor getting their first major role.

The word also appears in many phrases: a breakthrough is a major discovery, to break even means to avoid losing money, and a breakup is when a relationship ends.
