Past Simple

The Past Simple tense in English is used to talk about actions or states that started and finished at a specific time in the past. The time could be recent or distant, but the key is that the action is complete. This tense is often used when telling a story, describing past experiences or sharing facts about history.

In this guide, we'll explore what the Past Simple is, how to form it, when to use it, and common mistakes to avoid.

How to form

☑️ Affirmative sentences

Forming the Past Simple depends on whether the verb is regular or irregular. This is the most crucial concept to understand.

Rule 1: The formula for regular verbs — Subject + verb (+ed)
  • She worked hard yesterday.
  • They participated in the pet show.
  • I lived abroad for ten years.
Note: All the rules about adding -ed to verbs are discussed in another article
Rule 2: The formula for irregular verbs — Subject + irregular verb (past tense form)

Unfortunately, irregular verbs don't follow the '-ed' rule. They have their own unique past forms that must be memorized.

  • She went to the store this morning.
  • He ate a big sandwich for lunch.
  • We swam a lot while we were on holiday.
Rule 3: The formula for the verb 'to be' — Subject + was/were

This verb doesn't follow the standard rules. It has two past forms: 'was' and 'were'. The form you use depends on the subject of the sentence.

  • I/He/She/It + was → She was at home last night.
  • You/We/They + were → They were excited about the pet show.
❌ Negative sentences

To form such sentences we use the auxiliary verb 'did' followed by 'not' and the base verb. You can also use contracted forms of negative sentences when the auxiliary verb 'did' is combined with 'not' and becomes – didn't.

Rule 1: The formula for most verbs — Subject + did + not + base verb
  • I did not (didn’t) walk to the park.
  • She did not (didn't) eat the sandwich.
Rule 2: The formula for the verb 'to be' — Subject + be + not
  • He was not (wasn't) at the office.
  • They were not (weren't) hungry.
❔ Questions

To form a question, we also use the auxiliary verb 'did'. It comes before the subject.

Rule 1: The formula for most verbs — Did + subject + base verb
  • Did she work yesterday?
  • Did they go to the market?
Rule 2: The formula for the verb 'to be' — Be + subject
  • Was he at the party?
  • Were they in Belarus last December?
