Past
Simple
Finished, and you know when? Add -ed to regular verbs, use the second form of irregular ones; did helps with negatives and questions.
For teachers
- Start with “What did you do yesterday?” Each student says three sentences: I watched TV. I ate pizza. I went to bed late. Regular and irregular verbs mix naturally, and the class works with examples from its own life.
- Build an irregular verb wall. Put the 20 most frequent irregular verbs (go, have, do, see, take, buy, eat, make, get, come…) on the wall as first and second forms. Ask two or three aloud each lesson. Frequent short recycling beats memorising a long list.
- Catch “didn't went” before it appears. Draw two columns on the board: positive (V2) and negative (didn't + V1). Ask students to write the same sentence in both. Seeing the difference reduces the mistake.
- Guessing game: a student starts “Yesterday I…” but doesn't finish. The class asks Did you…? questions. The question pattern becomes automatic inside the game.
- Draw a timeline. “Now” at the right, “yesterday, last week, 2019” at the left: that is past simple territory. You can use the same line later to separate it from the present perfect.
- Do the “Type it” level with books closed. Students decide for themselves whether the verb is regular or irregular.

What it's for
The main use: an action that started and finished in the past. I watched a film last night. She moved to Ankara in 2019. The time is past and finished. Even without a time word the speaker thinks of the action as over: We visited the museum.
Positive sentences: V2. Regular verbs add -ed: play → played, watch → watched. Irregular verbs have their own second form: go → went, see → saw, buy → bought. The verb stays the same with every subject: I went, she went, they went.
Negatives and questions: did + V1. Did already carries the past, so the main verb goes back to its base form: I didn't go. Did you go? Putting both didn't and V2 together (didn't went) is the most common mistake. Short answers: Yes, I did. No, I didn't.
The verb be is different: was / were. I was, he was, she was, it was and you were, we were, they were. The negative is wasn't / weren't and questions start with the verb: Were you at home? Was she tired? Did is not used here.
Events told in order and past habits are past simple too. I woke up, had breakfast and left. Repeated actions in the past: When I was a child, we visited my grandparents every summer. Handy clues: yesterday, last week, in 2015, two days ago. The present perfect cannot go with these words.
The patterns side by side
| Positive (regular) | verb + -ed | I played football. She watched TV. |
| Positive (irregular) | the second form | I went home. They saw a film. |
| Negative | didn't + V1 | I didn't go. She didn't like it. |
| Question | Did + subject + V1? | Did you go? Where did he live? |
| Short answer | Yes, I did. · No, I didn't. | Did she call? Yes, she did. |
| The verb be | was / were · wasn't / weren't | I was tired. Were you at home? |
Signals: which tense?
Don't skip the last two rows: those words ask for the present perfect, not the past simple. Topic 2 on this site teaches you to tell the two apart in detail.
Common mistakes
and who tends to make themThese eight mistakes turn up in classrooms everywhere. Most come from two sources: forgetting that did carries the past, or writing did and V2 together. Under each one you'll see who tends to make it.
Why: Didn't already carries the past, so the main verb stays in its base form. You don't show the past twice: didn't go, didn't like, didn't see.
Who makes it: Learners at every level who put the ending on both the auxiliary and the verb, especially after learning past negatives.
Why: The same rule in questions: Did + subject + V1. Did shows the past, and the verb stays in its base form.
Who makes it: The same learners, in questions. Speakers of languages with a single marked verb often copy that pattern.
Why: Adding -ed to everything is a natural guess, but common verbs such as go, buy, see, eat, take are irregular: went, bought, saw, ate, took. Learning the 20–30 most frequent irregular verbs removes most of these errors.
Who makes it: Beginners and young learners who have just discovered the -ed rule and apply it to every verb.
Why: When you name a finished time such as yesterday, last week, two days ago, in 2019 you need the past simple. The present perfect (have seen) can't sit next to these words.
Who makes it: Speakers of French, German, Italian and Spanish, where a perfect form is normal for finished events in speech.
Why: After a question word (where, what, when) you still need did + subject + V1. In many languages the word order stays as in a statement; in English the auxiliary comes forward.
Who makes it: Beginners from languages where a question keeps statement word order and only the intonation or a small word changes.
Why: Be born is a one-time event in the past: was / were born. Learn was born as a fixed chunk. (I am born is a common mistake from many first languages.)
Who makes it: Learners who translate word for word and use the present of be with born, or leave be out (I born).
Why: The verb be has its own past: was / were. Questions and negatives use the verb itself, not did: Were you…? I wasn't…
Who makes it: Learners who have just learned that every past question begins with did and apply it to be as well.
Why: A short vowel plus one final consonant doubles the consonant: stop → stopped, plan → planned. A consonant plus y changes y to i: study → studied, cry → cried. Verbs ending in e just add d: like → liked.
Who makes it: Learners from languages with very regular spelling, who treat -ed as a fixed ending.
