What Is the Past Tense of Teach?
The past tense of teach is taught. It is an irregular verb, so it does not follow the standard pattern of adding -ed. You say taught for both the simple past and the past participle. For example: Yesterday, she taught a class on grammar. And: She has taught at that school for ten years.
Quick Answer
- Base form: teach
- Past tense: taught
- Past participle: taught
- Present participle / gerund: teaching
- Third person singular: teaches
Use taught when talking about a finished action in the past. Use has/have taught or had taught for perfect tenses.
Why Is It Irregular?
Many common English verbs are irregular because they come from Old English. Teach changed from tæcan in Old English, and its past form taught developed through a vowel change rather than adding a suffix. This is similar to verbs like catch (caught) and buy (bought). You simply have to memorize these forms.

Common Mistakes with Taught
Mistake 1: Using “teached”
Incorrect: He teached me math.
Correct: He taught me math.
Teached is not a word in standard English. Always use taught.
Mistake 2: Confusing Past Tense and Past Participle
Some learners think the past participle is different, but it is the same: taught. For example: I have taught (present perfect) and I had taught (past perfect) are both correct.
Mistake 3: Forgetting the Vowel Change
Incorrect: She teached the class last week.
Correct: She taught the class last week.
The vowel changes from ea to au. Practice saying teach and taught aloud to remember the difference.
Mistake 4: Using “taught” with a Present Meaning
Incorrect: I taught English every day. (if you mean a current habit)
Correct: I teach English every day. (present simple for habits)
Use taught only for past actions.
Better Alternatives and When to Use Them
Sometimes taught is the best word, but in certain contexts, you might choose a more precise verb:
- Instructed – More formal. Use in official reports or academic writing. “The instructor instructed the trainees on safety procedures.”
- Trained – Focuses on skill development. “She trained the new employees on the software.”
- Coached – Implies personal guidance, often in sports or performance. “He coached the team on their passing technique.”
- Educated – Broader, more formal. “The program educated the public about nutrition.”
- Mentored – Long-term, one-on-one guidance. “She mentored several junior researchers.”
Use taught when the context is general teaching or learning. Use alternatives when you want to emphasize the method or formality.
