The word quarter has several meanings:

1. One of four equal parts of something. When you cut a pizza into quarters, each slice is one fourth of the whole pie. In sports, many games are divided into quarters: a basketball game has four quarters, each lasting twelve minutes in the NBA. A school year often has four quarters, with report cards coming at the end of each one.
2. A US coin worth 25 cents, or one fourth of a dollar. The quarter shows George Washington's profile and is one of the larger coins Americans use regularly. Two quarters make 50 cents, and four make a dollar.
3. A district or neighborhood, especially in a city. The French Quarter in New Orleans is famous for its music and distinctive architecture. Many cities have historic quarters where older buildings are preserved. The word suggests a section of a city with its own character or purpose.
4. To provide lodging or housing for someone. Soldiers are quartered in barracks, meaning that's where they live. A general might quarter troops in a town during wartime. The Third Amendment to the US Constitution says the government can't force citizens to quarter soldiers in their homes, a complaint colonists had against British rule.
