The past simple talks about finished actions and finished events in the past. It often shows a clear past time. We use it when the action is complete.

The past simple often uses time expressions that show a finished time. These words and phrases place the action in the past. They help the listener know when the action happened.

Many verbs make the past simple with -ed. This form is the same for all subjects. It shows a completed action in the past.

Verb	Form
walk	walked
play	played
open	opened
watch	watched
clean	cleaned

Some regular verbs change spelling before -ed. These changes help keep the correct form. The rule depends on the last letter or letters of the verb.

Some verbs do not make the past simple with -ed. These verbs have special past forms. Learners need to know and remember these forms.

Verb	Form
go	went
have	had
do	did
eat	ate
see	saw
make	made

In affirmative sentences, we use the past simple verb form. The verb does not change for different subjects in the past simple. Regular verbs use -ed forms, and irregular verbs use their special past forms.

Subject	Form
I	worked
you	worked
he	worked
we	worked
they	worked

In negative sentences, we use did not or didn't with the base verb. The main verb does not use the past form after did. Did carries the past meaning.

In questions, did comes before the subject. The main verb stays in the base form. This structure asks about a finished action or event in the past.

You can now talk about completed actions and finished past events with the past simple. You can use past time expressions, regular and irregular past forms, and past simple statements, negatives, and questions.
