School is a place where students gather to learn from teachers. School is where you spend years mastering reading, writing, mathematics, science, and countless other subjects that help you understand the world. It's where you learn to work with others, solve problems, and discover what you're good at.

School can also describe a large group of fish swimming together, like a school of tuna. These fish move as one coordinated group for protection and efficiency, much like students moving through the hallways between classes.

In another sense, you can school someone by teaching them something thoroughly or even by defeating them decisively. If you beat your older brother at chess three games in a row, you might say you schooled him. This usage has a slightly competitive edge to it, suggesting that the lesson was memorable.

When something is described as old school, it means it follows traditional or classic methods. An old school coach might focus on fundamentals and discipline, while someone who is new school embraces modern approaches and technology.
