The past simple is the tense of finished actions at a specific time — yesterday, last week, in 2020. It's the backbone of storytelling in English: one completed event after another. This lesson breaks down exactly how to form it, when to use it instead of the present perfect, and the mistakes that trip up even confident learners.

Subject + verb + -ed (or irregular past form)
Subject + didn't + base verb
Did + subject + base verb?

A specific, finished action at a definite point in the past — with no ongoing connection to now.
Example: I visited Paris in 2019. (A single, finished action.)
Completed Actions
A single action that started and finished in the past.
Sequences of Events
Telling a story — one completed action after another.
Past Habits and States
Repeated actions or ongoing states that are now finished.
Historical Facts
Events that are simply true about the past.
Irregular verbs must be memorised
Many of the most common verbs are irregular: go → went, see → saw, eat → ate, write → wrote. There's no shortcut — regular practice and memorisation are the best ways to learn them.
Spelling changes for regular -ed verbs
Verbs ending in -e just add -d (like → liked); one-syllable verbs ending in a single vowel + consonant double the consonant (stop → stopped) — but longer verbs stressed on an earlier syllable don't (visit → visited, not visitted); verbs ending in consonant + y change y to -ied (study → studied).

I did went to school.
I went to school.
Positive past simple sentences don't use did at all — just the past form directly. Did only appears in negatives and questions.
She goed home early.
She went home early.
Go is irregular — its past form is went, not goed.
I have visited Paris in 2019.
I visited Paris in 2019.
A specific finished time (in 2019) needs the past simple, not the present perfect.
Did you saw the film?
Did you see the film?
After did in a question, the main verb stays in its base form — see, not saw.

The key question: does the exact time matter?
| Feature | Past Simple | Present Perfect |
|---|---|---|
| Time reference | Specific, finished time | Unspecified or unimportant |
| Connection to now | No connection — it's just a past fact | Result still matters now |
| Typical time words | yesterday, last week, in 2020, ago | ever, never, just, already, yet, for, since |
| Common use | Completed actions, stories, sequences of events | Life experiences, news, unfinished time |
Use the past simple (verb+ed or an irregular form) for actions that started and finished at a specific time in the past. Reach for time words like yesterday, last week, and in 2020 — and switch to the present perfect the moment the exact time isn't stated.

Past simple describes a completed action at a specific, finished time (I visited Paris in 2019). Present perfect connects a past action to now and is used when the exact time isn't stated (I have visited Paris).
Most English verbs are regular (add -ed). Irregular verbs have unique past forms you need to memorise — common ones include go/went, see/saw, eat/ate, and have/had. There's no reliable rule; it comes from practice and exposure.
Not usually — since and for typically pair with the present perfect (I have lived here for five years). The past simple pairs with specific time words like yesterday or in 2020.
Did is used with the past simple of action verbs in questions and negatives (Did you go?). Was/were is the past form of to be, used on its own (I was tired) or in the past continuous (I was working).
No — did is only used in negatives (didn't) and questions. Positive sentences just use the past form directly: I went, not I did went.
Yes, the core rules are identical. The main difference is that American English uses the past simple more often in situations where British English would use the present perfect.
