What does teach mean?
To teach is to help another person acquire knowledge, understanding, or a useful skill. A teacher may explain a subject, demonstrate a procedure, offer guidance, or provide experiences through which a lesson becomes clear. The word is used in schools and universities, in vocational and professional training, and in less formal situations such as teaching a friend a game or showing someone how to perform a task. Its basic construction is “teach someone something” or “teach someone how to do something.” Teach can also mean “learn through experience,” as in a story that teaches caution. The term is generally neutral, although telling someone something they already know may sound patronizing. Although “learn” is often treated as its opposite, the two actions are complementary: learning usually involves instruction, guidance, or experience. Teach is also notable for the irregular past tense and past participle “taught,” which contrasts with its otherwise regular appearance.

"The course teaches students how to interpret primary sources."

Teach looks as though it should form its past tense regularly, but the surprising answer is simply “taught.”

Where does teach come from?
Teach descends from Old English tǣcan, meaning “to instruct” or “educate,” and is related to other Germanic forms such as Dutch leren and German lehren. Its deeper roots connect with the Indo-European family of words associated with showing, indicating, or pointing out, including indicate, index, and token. The modern meaning developed from the older sense of directing instruction and imparting knowledge.

How teach is actually used
The word is neutral in register and is especially associated with schools, tutoring, and the communication of practical knowledge. It can sound mildly patronizing when directed at someone who already understands the subject. “Learn” is its conventional contrast, although the two words are complementary rather than exact logical opposites: a teacher teaches, while a learner learns.
