The past simple

Start with a past event or state

An event is something that happens. A state is how something is: where you live, what you know or how you feel. The past simple can describe both.

• Our neighbours painted their gate on Sunday. A past event.
• I knew the answer yesterday. A past state of knowledge.

In the ordinary past-time use, you present the event or state as part of a past period. It need not be short: a repair can take ten minutes, and a stay can last several years. A result can still matter now even when the event is in the past.

You do not need to learn every later use before you can say what you did yesterday.

Positive forms: regular and irregular

The base form is the verb without an added ending: help, open, go. A regular verb forms its past with -ed, with spelling changes where needed. An irregular verb has a past form you learn separately.

The subject is the person or thing the sentence is about. With ordinary verbs, the past form does not change with the subject. There is no extra -s for he, she or it.

Main-verb be is different: I/he/she/it was; you/we/they were. It also forms questions and negatives differently. Was and were: the past of be explains its full system.

Spelling regular past forms

These spelling patterns apply to regular verbs. They do not turn an irregular verb into a regular one.

Vowels are the letters a, e, i, o, u; consonants are the other letters in these patterns. Pay and say are irregular exceptions to the vowel + y pattern: paid, said.

When the last consonant doubles

Compare the short-vowel patterns hop, hopped and rub, rubbed. The final consonant doubles before -ed. In longer words, the final stress matters: stress is the stronger part you hear in a word.

Do not apply a short spelling rule to every word without checking its pattern. British and American spellings can differ: British travelled and American traveled are accepted forms. Spelling rules for verbs and plurals, and short forms covers wider spelling patterns and exceptions.

How to say -ed

The spelling -ed has three possible sounds. Use the last sound of the base verb, not only its last letter. The symbols between slashes show sounds.

A voiced sound uses vibration in your throat; a voiceless sound does not. The /ɪd/ group adds a syllable, a separate beat: want-ed. Do not add that extra beat to every -ed word. The ending of washed is /t/, not a separate ed syllable.

Cambridge's table and the BBC pronunciation explanation support the three groups. This is a pronunciation rule for regular -ed forms, not a way to predict an irregular verb's past form.

Irregular past forms to learn

Learn the base and past form together. Some change a little, some change a lot, and some keep the same spelling. This is a useful selection, not a complete verb list.

The past of read has the same spelling but sounds like the colour red, /red/. Put has the same written past form as its base form. A past sentence does not always contain a visibly different verb ending.

• The visitor put her bag beside the chair. Past put, with no -ed.
• We read the instructions before lunch. Here read is pronounced /red/.

Negatives with did not or didn't

Use did not, or its short form didn't, before the base form. The helper did carries the past meaning; the main verb returns to the base form. This works with regular and irregular verbs.

• The driver didn't notice the new sign.
• We did not take the lift.

Do not keep a second past form after didn't: didn't take, not didn't took. Do not add to: didn't take, not didn't to take.

Be is different

With main-verb be, use was not/wasn't or were not/weren't, not didn't be in the ordinary past description.

These pairs are related in meaning but use different grammar. Open in the first left sentence is a verb; open after wasn't describes the office's state.

Questions and short answers

For an ordinary yes/no question with a main verb other than be, put did before the subject. Then use the base form.

• Did the courier bring the documents?
• Where did your cousins stay?
• Why didn't the alarm ring? A negative question.

A short answer repeats did or didn't, not the main verb. Match the answer's subject to the person or thing you are answering about.

Main-verb be does not use did here: Was the shop busy?, not Did the shop be busy? A short answer is Yes, it was or No, it wasn't.

Who did it, or who did you see?

In a neutral positive question, when who or what is the subject, use the past verb without did. When you ask about the object, keep did + subject + base form. The object is the person or thing affected by the verb.

This is not a ban on every subject question with did. Who didn't call? is negative. Who did call?, with stressed did, can insist on the answer. Cambridge explains both exceptions. Subject and object questions gives the wider system.

Uses in past time

An event, a repeated event or a state

You can tell someone about one event, several events, or a situation that was true for a period in the past. The context supplies the past time, with or without a date.

• The old heater stopped during the night. One past event.
• During that course, I cycled to the college every morning. Repeated past activity.
• My uncle owned that shop for twelve years. A past state over a period.

A past form locates the description in past time. Do not use it alone as proof of every fact about now. For example, She worked there in 2020 reports that period; the sentence does not itself tell you her complete employment history since then.

British Council introduces repeated events at beginner level.

Time expressions and shared context

Yesterday, last night and three weeks ago can locate a past event. Put ago after the amount of time; put last before the period.

• They replaced the lock four days ago.
• I visited the new gallery last month.

A time expression is not required in every past sentence. If someone asks about your journey, you can say The train arrived late because the journey is already understood. Cambridge explicitly includes past simple without a stated time reference.

Choose the tense from the intended time and meaning, not from a single signal word. Present perfect or past simple? compares past events with present-perfect viewpoints; Past continuous or past simple? compares a whole past event with an activity in progress.

A sequence in a story

Several past-simple verbs can move a story forward: you normally understand the events in the order given, unless other words show a different order.

• Nia opened the cupboard, took out a folder and closed the door.

Here opening comes first, taking out the folder comes next, and closing follows. This is different from describing the background with a past continuous. Narrative tenses: telling a story in the past develops that contrast.

When and other time links

A clause is a group of words with a subject and a verb. You can connect a past event to another clause with when.

• When the bell rang, the class went outside.

When does not by itself mean that an activity was already in progress. In this example, the bell is followed by the class leaving. Other situations need a different combination of forms.

They express different time relations, not one fixed order.

• We waited until the road opened. Until gives the endpoint of the wait.
• Once the lights came on, the audience sat down. One event leads into another.

Later uses: the form is not always past time

Imagined situations and wishes

A past form can describe an imagined present or future situation. It need not report an event that actually happened.

• If I lived nearer, I would visit more often. An imagined situation, not a past address.
• I wish this room had a bigger window. A wish about the room now.

The second conditional: unreal situations now or in the future and Wish and if only: wishes about now, the past and the future explain the complete patterns.

Less-direct requests

The context can make the request relevant now.

• I wondered if you could check this figure. A request you can make now.
• I wanted to ask about the opening hours. Introducing a current question.

Past forms after if can also make a request polite: I would be grateful if you sent me the details. Do not conclude that every past-simple sentence is polite or that every past form refers to now.

Did for emphasis and later inversion

In an ordinary positive statement, use the past form directly. For emphasis, you can use did + base form, stressing did: I did send the attachment. This can contradict a claim that you did not send it.

That is a useful ordinary-pattern contrast, not a complete ban: the later emphasis pattern is valid. Emphatic do, does and did explains it.

Did comes before the subject, and repair is the base form. Inversion for emphasis treats the wider pattern.

What comes next

Was and were: the past of be covers was/were. The past continuous and Past continuous or past simple? cover past activity in progress. Present perfect or past simple? compares past and present-perfect viewpoints. Used to for past habits and states develops past habits; Spelling rules for verbs and plurals, and short forms covers wider form changes. For later meanings, use The second conditional: unreal situations now or in the future, Wish and if only: wishes about now, the past and the future, Emphatic do, does and did and Narrative tenses: telling a story in the past.
