Past simple: was/were & regular/irregular verbs
A1 14 / 50
In short
We use the past simple to talk about a finished action or state at a finished time in the past (yesterday, last week, in 2010). The verb be has two past forms (was/were); other verbs add -ed (regular) or have a past form of their own (irregular: go -> went, put -> put).
The rule
1) Past of BE uses two forms:
| Subject | be (past) |
|---|---|
| I / he / she / it | was |
| you / we / they | were |
- Negative: wasn’t (was not), weren’t (were not).
- Questions: put be first - Was I…? / Were you…?
- For things that existed: there was (singular), there were (plural).
2) Other verbs (action verbs) have the same past form for every subject - no -s, no change for he/she/it.
- Positive: regular verb + -ed (work -> worked), or the special past of an irregular verb (go -> went).
- Negative: didn’t + base verb -> I didn’t go (NOT didn’t went).
- Question: Did + subject + base verb -> Did you see it?
The little word did/didn’t already shows past time, so the main verb goes back to its base (no -ed, no change) in negatives and questions.
Forms & patterns
Regular verbs - spelling of -ed
| Rule | Base -> Past | Note |
|---|---|---|
| most verbs: + -ed | work -> worked, play -> played | the basic rule |
| ends in -e: + -d | like -> liked, live -> lived | just add -d |
| consonant + -y: -y -> -ied | study -> studied, try -> tried | but play -> played (vowel + y) |
| one short stressed vowel + one consonant: double it | stop -> stopped, plan -> planned | also travel -> travelled (UK) |
Pronunciation of -ed (sound, not spelling):
| Sound | After base ending in… | Examples |
|---|---|---|
| /t/ | unvoiced sound (p, k, f, s, sh, ch) | worked, liked, washed |
| /d/ | voiced sound or vowel (b, g, l, n, r, vowels) | played, lived, called |
| /id/ | only base -t or -d | wanted, needed, started |
High-frequency irregular verbs (learn these first):
| Base | Past | Base | Past |
|---|---|---|---|
| go | went | come | came |
| have | had | take | took |
| do | did | know | knew |
| say | said | think | thought |
| see | saw | find | found |
| get | got | give | gave |
| make | made | tell | told |
Some irregular verbs do not change: put, let, set, cut, cost look the same in the past (I put it back yesterday) - you add nothing, so the words around them show the tense. read -> read is spelt the same too, but the past sounds like red.
Negatives & questions (regular AND irregular - same pattern):
| Type | Pattern | Example |
|---|---|---|
| Negative | subject + didn’t + base | She didn’t call me. |
| Yes/no question | Did + subject + base | Did they win? |
| Wh- question | Wh- + did + subject + base | Where did you go? |
Examples
| English | Note |
|---|---|
| I was tired after the trip. | be, singular subject -> was. |
| They were at home all day. | be, plural subject -> were. |
| There were ten people in the room. | plural things -> there were. |
| We watched a film last night. | regular verb + -ed; finished time. |
| She studied French at school. | consonant + y -> -ied. |
| He went to Rome in 2010. | irregular: go -> went; a finished year. |
| I didn’t see the email. | negative = didn’t + base (NOT didn’t saw). |
| Did you enjoy the party? | question = Did + subject + base. |
Common mistakes
- I didn’t went -> I didn’t go - after didn’t, use the base verb, not the past.
- Did you saw it? -> Did you see it? - did already shows past, so use the base.
- He was study / He studyed -> He studied - consonant + y becomes -ied.
- We was late -> We were late - we/you/they take were, not was.
- I goed / buyed / putted -> I went / bought / put - common verbs are irregular; learn them by heart.
Tips
- One past form fits all subjects (except be): I/you/he/we/they worked. No -s on he/she/it.
- The /id/ ending is only for verbs ending in -t or -d (wanted, needed). Everywhere else it’s a quick /t/ or /d/, not an extra syllable.
- Keep the “power” on did/didn’t: it carries the past, so the next verb relaxes back to its base.
- Make a small notebook of irregular verbs and add a few each week - they are the most common verbs in English.
