Past simple: regular and irregular verbs

Use the past simple to talk about actions and events that started and finished at a completed time in the past.

Overview

What this grammar does

Use the past simple to talk about actions and events that started and finished at a completed time in the past.

Form and rules

How it works

1

For regular verbs, usually add -ed: work → worked, play → played.

2

If a verb ends in -e, add -d: live → lived. If it ends consonant + y, change y to i and add -ed: study → studied.

3

Some short regular verbs double the final consonant: stop → stopped.

4

Irregular verbs have special forms: go → went, see → saw, have → had, buy → bought.

5

The positive past form is the same for every subject: I worked, she worked, they worked.

A closer look

Meaning and use

Use the past simple for completed actions and events in finished past time, often with expressions such as yesterday, last week, in 2024, or two days ago.

Regular verbs normally add -ed, while irregular verbs change form in different ways. The affirmative past form is the same for every subject.
