The Past Simple

The past simple is the tense of stories — it tells you what happened and finished. It's the one you reach for whenever you talk about a completed event in the past, and it's probably the tense you use most when you write. Where students come unstuck isn't the idea — everyone understands "it's over and done" — it's the forms. English has a tidy rule for most verbs and then a big pile of irregular ones that ignore it completely, and it's the mix that causes wobbles like "I goed" or "she runned." Sort the regular from the irregular, and this tense becomes rock solid.

The form: usually -ed

For most (regular) verbs, add -ed:

play → played · walk → walked · finish → finished

Watch a few spelling tweaks: a verb ending in -e just adds -d (like → liked); a short verb ending in one vowel plus one consonant doubles it (stop → stopped, plan → planned); and a consonant plus -y becomes -ied (cry → cried, carry → carried).

The irregular ones

Loads of common verbs don't follow the -ed rule — you just learn them:

go → went · see → saw · have → had · run → ran · buy → bought · make → made · take → took · come → came · think → thought

Nobody says goed or seed — your ear already knows most of these irregular forms. The trouble spots are the trickier ones (bring → brought, catch → caught, teach → taught), which are worth a bit of learning by heart.

What it's for

A finished action at a definite past time:

Yesterday I watched a film. Last week we went to the coast.

It's often paired with a past time word: yesterday, last night, in 2019, an hour ago, when I was little. It's also the natural tense for telling a story in order, one event after another:

She opened the door, stepped inside and switched on the light.

Watch out — questions and negatives use "did"

Here's the rule that catches the most people. To ask a question or make a negative, bring in did, and the main verb goes back to its plain form:

Did you go? — not Did you went?I didn't see it. — not I didn't saw it.She didn't come home. — not She didn't came home.

Why? Because did is already carrying the past — so the main verb doesn't need to as well. Putting the past on both (did… went) is doubling up, and that's the error to avoid.

Past simple vs present perfect

A quick contrast, because these two get muddled. Use the past simple when there's a finished time; use the present perfect when the time is unstated or it links to now:

I broke my arm last year. (definite past time — past simple)I've broken my arm. (no time given, it matters now — present perfect)

If you can point to when it happened, the past simple is your tense.

An edge case: "used to" and "would" for old habits

For things you did repeatedly in the past but don't any more, you can use used to or would: "I used to walk to school," or "Every summer we would visit my gran." These paint a habit rather than one single event. They sit happily alongside the plain past simple and add a nice "back then" flavour to storytelling.

A second angle: the "-ed" that hides its sound

One thing that quietly confuses people is that the -ed ending is spelt the same but said three different ways, and mixing up the spelling and the sound leads to slips. In walked it sounds like a t ("walkt"); in played it sounds like a d ("playd"); and in wanted or needed it adds a whole extra syllable ("want-id"). The important thing is that however it sounds, you always spell it -ed for regular verbs — never walkt or playd. Your ear can trick your hand here, so trust the rule: regular past simple is -ed on the page, full stop. The same goes the other way with irregular verbs, where there's no -ed at all to lean on — went, saw, bought just have to be known. If you're ever unsure whether a verb is regular, try adding -ed and saying it: if "catched" or "teached" sounds childish, that's your ear telling you it's one of the irregulars to learn by heart.

Why it matters

The past simple is the engine of almost every story and recount you'll ever write, so getting its forms automatic pays off constantly. The two things markers notice most are irregular slips ("he catched the ball," "we runned home") and the double-past error after did ("did she went?"). Both are easy to fix once you know the pattern, and fixing them lifts a piece from "muddled" to "controlled" in a single stroke. Keeping your tense steady across a whole story — not drifting into the present halfway through — is one of the clearest signs of confident writing. It's also the tense you'll use to recount real events in history, science write-ups and personal accounts, so getting its forms secure pays off far beyond storytelling; almost every "what happened" answer you ever write leans on it.
