Teach means to give instruction to a person or group, to help someone learn a subject or skill, or to cause someone to understand something through experience or example. She started teaching English to children after completing her language certificate.
What Does Teach Mean?
Teach comes from Old English tǣcan, meaning "to show, point out, or instruct", related to tācn (sign, token) — the same root that gives us the modern word token. The word has been central to English since its earliest written records, reflecting how fundamental the act of instruction is to human society.
In contemporary English, teach is used in three closely related ways. First, it describes the professional activity of an educator: She teaches maths at a secondary school. Second, it describes passing on a specific skill or piece of knowledge: My grandfather taught me to fish. Third, it describes learning through experience rather than formal instruction: Failure teaches us more than success.
Note that teach is an irregular verb. Its past simple and past participle are both taught (/tɔːt/), not teached — a very common mistake among learners at every level.
