Pros are the advantages or positive aspects of something. When you're trying to decide between two options, listing the pros helps you see what's good about each choice. If you're debating whether to join the soccer team, the pros might include getting exercise, making new friends, and learning teamwork. The pros of reading before bed might be that it helps you relax and improves your vocabulary.

People often talk about “weighing the pros and cons,” which means carefully considering both the good points (pros) and the bad points (cons) before making a decision. Your family might weigh the pros and cons of getting a dog: the pros could be companionship and fun, while the cons might be the cost and responsibility of daily care.

The word pro can also mean a professional or expert at something, like a tennis pro or a golf pro, but that's a different meaning.
