Is it teached or taught?
The past tense of the verb teach is taught. Teach is an irregular verb, so it doesn’t use the “-ed” ending for the past tenses.
Taught is both the simple past tense form and past participle. The past participle is used to form the perfect tenses (e.g., “I have taught English across the whole age range”) and the passive voice (e.g., “I think we have all been taught a lesson today”).
