Past Simple

What is the Past Simple Tense?

The Past Simple is one of the most essential tenses in the English language. It is strictly used to talk about:
- Completed actions occurring at a specific time in the past.
- A chronological sequence of events that happened one after another.
- Past habits and states that no longer exist.

The defining feature of the Past Simple is that the action is 100% finished and completely disconnected from the present. We either know exactly when the action happened, or it is heavily implied.

Past Simple Structure and Formula

How to Form the Past Simple: Positive Sentences

To form a positive sentence, you must change the base verb into its past tense form. For regular verbs, you simply add -ed.

Formula: Subject + Past Verb (V-ed) + Object
(S + V-ed / V2 + O)

Examples:

She worked (S + V-ed/V2) late yesterday.
They arrived at midnight.

Irregular Verbs:
Many of the most common verbs in English are irregular. You cannot add "-ed" to them; you must memorize their specific past form (referred to as V2).

She went (S + V2) to the market this morning.
I had a great time at the party.

How to Form the Past Simple: Negative Sentences

For all verbs (both regular and irregular), the negative form uses the auxiliary verb did not (didn't) combined with the base verb. A massive mistake learners make is trying to put the past tense onto the base verb. The word "did" already holds the past tense.

Formula: Subject + did not (didn't) + Base Verb
(S + didn't + V + O)

I didn't enjoy (S + didn't + V) the film.
He didn't come to work yesterday.

How to Form the Past Simple: Questions and Short Answers

For a yes/no question, use the auxiliary did before the subject.

Formula: Did + Subject + Base Verb?
(Did + S + V + O?)

Wh- Questions Formula: Wh- word + did + S + V(Base)?

Where did you go last night?
What did she say?

When to Use the Past Simple Tense in English

1. A Completed Action at a Specific Time in the Past

This is the most common use. The time must be known.

I visited my parents last weekend.
She graduated in 2019.
Columbus arrived in the Americas in 1492.

2. A Sequence of Completed Past Events

When telling a story chronologically, use a chain of Past Simple verbs.

I woke up, had a shower, made coffee, and left the house.
She walked into the room, looked around, and sat down.

3. Past Habits and States

Things that were true for a wide period of time historically.

When I was a child, I played football every day.
She lived in London for five years.

Frequently Asked Questions

Why do I say "She didn't go" instead of "She didn't went"?

In English verbs, the auxiliary handles the heavy lifting of showing the tense. The word "did" is inherently the past tense. Because you already showed the past tense using "didn't", the main action verb returns to its normal base form. Double-past-tense verbs (didn't went) are completely prohibited.

Do I need to use "did" if the question asks "Who"?

No. If "Who" represents the subject performing the action, you bypass the auxiliary completely and just conjugate the main verb.
- Incorrect: Who did tell you?
- Correct: Who told you?

Can I mix Present and Past simple in the same sentence?

Yes, but only if you are contrasting facts over time. Example: "I live in New York now, but I grew up in Tokyo."
