The past simple describes something that happened and finished in the past: “I visited my grandmother last weekend.” Regular verbs add -ed (visit → visited), while irregular verbs have their own past form that needs to be learned (go → went). Negatives and questions use “did”, and the main verb goes back to its base form.

## Regular verbs: the -ed ending

Most verbs add -ed: play → played, watch → watched. If the verb ends in -e, add only -d: like → liked. If it ends in a consonant + y, the y becomes i: study → studied. Short one-syllable verbs ending in a single vowel + a single consonant double the last letter: stop → stopped (but rain → rained, play → played).

## Irregular verbs

Many common verbs are irregular: go → went, eat → ate, see → saw, buy → bought, have → had, make → made. Instead of memorising them from a list one by one, it is easier to learn them inside your own sentences: “I bought a new bag.”, “We ate pizza.”

## Negatives and questions

In negatives, use “didn't” and keep the verb in its base form: “She didn't go to school.” (not “didn't went”). In questions, “Did” comes first: “Did you see the film?” Short answers: “Yes, I did.” / “No, I didn't.” The verb “be” is different: it uses “was/were” and does not need “did”: “Were you at home?”

## A short exercise

Write three things you did last weekend: “Last weekend I…”. Then add one thing you didn't do with “I didn't…”, and prepare one “Did you…?” question for a friend. Mark which verbs are regular and which are irregular.

## Frequently asked questions

### How should I learn irregular verbs?

Start with the most common ones instead of long lists and use each one in a sentence of your own: “I went to the market.”

### Why don't we say “didn't went”?

“Did” already shows the past, so the main verb stays in its base form: “I didn't go.”
