To teach means to help someone learn or understand something new. When your math teacher explains fractions, when your dad shows you how to change a bike tire, or when you help your younger sibling sound out words in a book, you're all teaching.

Good teaching requires knowing something yourself and finding ways to make it clear and interesting to others. A great teacher adjusts their approach when students are confused. They might use examples, stories, demonstrations, or hands-on practice. They watch for signs that someone understands or needs more help.

The word comes from an Old English word meaning “to show” or “to point out,” which captures something important: teaching is about showing people how to see or do something they couldn't before. You can teach facts, skills, or even attitudes. A coach teaches strategy, a musician teaches technique, and sometimes life experiences teach us lessons about patience or perseverance.

Anyone can be a teacher in the right moment. When you share what you know with others, you're teaching. The best teachers remember what it felt like not to understand something, which helps them explain it to people who are learning it for the first time.
