Past Simple Tense

What Is the Past Simple?

The past simple tense describes actions that started and finished in the past. The action is complete — it is over.

• I visited Paris last summer. (The visit is finished.)
• She called me yesterday. (The call is over.)

How to Form the Past Simple

Regular Verbs

Add -ed to the base form of the verb:

• work → worked
• play → played
• want → wanted
• live → lived (just add -d if the verb ends in -e)
• study → studied (consonant + y → change y to -ied)
• stop → stopped (short vowel + consonant → double the consonant)

Irregular Verbs

Many common verbs have irregular past forms. You must memorize these:

Good news: The past simple form is the same for ALL subjects (I, you, he, she, it, we, they).

Negative Sentences

Use did not (didn't) + base form of the verb:

• I didn't go to school yesterday.
• She didn't call me.
• They didn't know the answer.

Important: After "didn't," always use the base form — NOT the past form.

• Correct: I didn't see him.
• Wrong: I didn't saw him.

Questions

Use Did + subject + base form:

• Did you go to the party? — Yes, I did. / No, I didn't.
• Did she finish her homework?
• Did they enjoy the movie?

Questions with "Was/Were"

For the verb "to be," don't use "did":

• Was he at home? — Yes, he was.
• Were you tired? — No, I wasn't.

Time Expressions for Past Simple

• yesterday — I saw her yesterday.

• ago — He moved here two years ago.
• in 2020 — She graduated in 2020.
• when I was young — When I was young, I played outside every day.
