Talking about completed past actions (simple past tense)

The simple past, also called the past simple, describes actions, events, or states that started and finished at a definite time in the past. Use it for completed actions when the time is known, given, or understood.

- I visited my grandparents last weekend.
- She graduated in 2015.
- They left an hour ago.

What is the simple past tense?

The simple past expresses that something happened and is finished. It is the basic tense for telling stories, listing past events, and describing past habits or facts that no longer apply.

Examples:

- I saw that movie yesterday.
- He lived in Canada for two years.
- We often walked to school when we were children.

When do I use the simple past?

Completed actions at a specific time

Use the simple past when the speaker gives a definite time or when the moment is clear from context.

- I finished the report yesterday.
- She visited Tokyo in 2018.
- They left two hours ago.

Sequence of events / narration

Use the simple past to list events that happened one after another in the past.

- I woke up, made coffee, and left the house.
- He opened the door, looked around, and smiled.

Past habits and repeated actions

Use the simple past to describe habits that occurred regularly in the past.

- When I was a child, I played piano every day.
- We often went camping in summer.

Note: To emphasize that a habit no longer happens, you can also use used to or would: I used to smoke; When I was young, we would visit our grandparents every Sunday.

Finished past states or facts

Use the simple past for situations that were true in the past but are finished now.

- He lived in Brazil for five years (but he doesn’t live there now).
- The shop closed in 2012.

How do I form the simple past?

Regular verbs: add -ed

Most verbs form the past by adding -ed to the base form. The form is the same for all subjects.

- talk → talked
- play → played
- work → worked

Examples in sentences:

- I talked to her yesterday.
- We played tennis on Saturday.
- She worked late last night.

Spelling rules for regular verbs

- If the verb ends in -e, add only -d: love → loved.
- If the verb ends in consonant + y, change y to i and add -ed: cry → cried; but if vowel + y, just add -ed: play → played.
- For one-syllable verbs that end consonant-vowel-consonant (CVC) and are stressed, double the final consonant: stop → stopped; plan → planned.
- Verbs ending in -c add -ked: panic → panicked; picnic → picnicked.

Examples:

- love → loved (I loved that book.)
- cry → cried (She cried at the movie.)
- stop → stopped (We stopped the car.)
- picnic → picnicked (They picnicked last Sunday.)

Irregular verbs

Many common verbs are irregular. They do not follow the -ed pattern and must be learned individually or checked in a dictionary. Here are some common irregular verbs with example sentences:

- be → was / were : I was late. They were at home.
- have → had : She had a sandwich.
- do → did : He did his homework.
- go → went : We went to the beach.
- see → saw : I saw a great film.
- come → came : She came early.
- get → got : They got a new car.
- make → made : I made dinner.
- take → took : He took the train.
- say → said : They said hello.
- know → knew : I knew the answer.
- think → thought : She thought about it.
- find → found : We found the keys.
- give → gave : He gave me a pen.
- tell → told : She told a story.
- leave → left : I left early.
- put → put : He put the book on the table.
- read → read (pronounced like red) : I read that book last month.
- buy → bought : I bought new shoes.
- bring → brought : He brought coffee.
- win → won : She won the prize.
- lose → lost : We lost the match.

Example sentences with irregular verbs:

- I went to the store this morning.
- She wrote three emails yesterday.
- They met at noon.

How do I make negatives and questions in the simple past?

Negatives

To make a negative for most verbs use did not (didn't) + base form of the verb. The main verb stays in its base form after did not.

- I did not (didn't) see him yesterday. (NOT I didn't saw him.)
- She didn't call me.

Exception: the verb be is negative with wasn't / weren't (no did):

- He wasn't at home.
- We weren't ready.

Questions and question words

To form a yes/no question use did + subject + base verb.

- Did you finish the homework?
- Did they arrive on time?

For questions with question words, put the question word first, then did + subject + base verb:

- When did you arrive?
- Where did she buy that jacket?

For the verb be, invert be and the subject to form a question:

- Was he at the party?
- Were they happy?

Short answers and tag questions

Short yes/no answers:

- Did you call her? Yes, I did. / No, I didn't.
- Was she late? Yes, she was. / No, she wasn't.

Tag questions use didn't for ordinary verbs and wasn't/weren't for be:

- You saw the film, didn't you?
- She was at the meeting, wasn't she?

What are common time expressions with the simple past?

Common time expressions that signal the simple past:

- yesterday
- last night / last week / last year / last summer
- two days ago / an hour ago
- in 2010 / in April
- on Monday / on July 3rd
- at 5 pm

Examples:

- I called you yesterday.
- They moved here last year.
- She arrived two hours ago.
- He was born in 1992.
- We met on Tuesday.

Note on for and since

- Use simple past with finished situations: I lived there for five years (and I don't live there now).
- Use present perfect when the situation continues to the present: I have lived here for five years (and I still live here).

How is the simple past different from other past tenses?

Simple past vs present perfect

- Simple past: completed action at a definite time.
- I visited Rome in 2010.
- Present perfect: action at an unspecified time before now or with present relevance.
- I have visited Rome. (Experience; no date given)

Common mistake to avoid: do not use present perfect with definite past time words. Wrong: I have seen him yesterday. Correct: I saw him yesterday.

Simple past vs past continuous

- Use past continuous for an action in progress in the past, and simple past for shorter actions that interrupt or for completed actions.

- I was reading when the phone rang. (reading = background in past continuous; rang = interrupting simple past)
- I read the report and then I wrote the summary.

Simple past vs past perfect

- Use past perfect for an action that happened before another past action.

- By the time I arrived, they had already left.
- She had finished her homework before dinner.

Simple past vs used to

- Both can describe past habits, but used to emphasizes a habit that no longer happens.

- I lived in Mexico when I was a child. (simple statement of past fact)
- I used to live in Mexico. (emphasizes that it is no longer true)

Pronunciation of -ed endings

The -ed ending has three pronunciations in regular past verbs:

- /ɪd/ or /əd/ after verbs that end with the sounds /t/ or /d/: wanted /ˈwɒn.tɪd/, decided /dɪˈsaɪ.dɪd/.
- /t/ after verbs that end in an unvoiced consonant sound (for example /p/, /k/, /f/, /s/, /ʃ/, /tʃ/): stopped /stɒpt/, watched /wɒtʃt/.
- /d/ after verbs that end in a voiced sound (vowel or voiced consonant): played /pleɪd/, robbed /rɒbd/.

Irregular note: read in the past is spelled the same but pronounced /rɛd/ (red) as in I read that book last month.

Common mistakes to avoid

- Using present perfect with a definite past time: I have been there yesterday (wrong). Correct: I was there yesterday.
- Using did + past form in questions or negatives: Did you saw the show? or I didn't went (both wrong). Correct: Did you see the show? I didn't go.
- Using incorrect irregular forms: I have went (wrong). Correct: I went or I have gone (depending on meaning).
- Spelling errors with -ed: stoped (wrong) → stopped (correct).
- Using did with be: Did you were at the party? (wrong). Correct: Were you at the party? or Did you go to the party?

Glossary

- Base form: the verb without to, for example: go, see, write.
- Regular verb: a verb that forms the past with -ed, for example: talk → talked.
- Irregular verb: a verb that has a special past form, for example: go → went.

- Signal words: words that often indicate which tense to use, for example: yesterday, last week, ago.
- CVC: consonant-vowel-consonant pattern, used in spelling rules for doubling the final consonant.

Quick summary

- Use the simple past for actions completed at a definite time in the past.
- Form regular verbs by adding -ed; learn irregular verbs separately.
- Negatives and questions use did + base verb (except be).
- Common time words: yesterday, last, ago, in + year, on + day.
- Do not use present perfect with definite past time expressions.

If you remember these points and practice the common irregular verbs, you will be able to talk clearly and correctly about completed past actions.
