Simple explanation
What are irregular verbs? We use the past simple to talk about actions and events that happened and finished in the past. Many English verbs form the past simple by adding -ed, but some common verbs do not follow this rule. They have different past forms. For example, the past form of go is went, not goed. These verbs are called irregular verbs. Common irregular verbs to learn first There is no single rule for forming all irregular past forms, so you need to learn them gradually. At A1 level, focus on common verbs that you can use in everyday situations. Important examples include go → went, come → came, see → saw, eat → ate, drink → drank, have → had, get → got, make → made, take → took and buy → bought. Affirmative sentences In an affirmative past simple sentence, use the past form of the irregular verb after the subject. The form is the same for all subjects. We say I went, she went and they went. You do not add -s for he, she or it in the past simple. Negative sentences To make most past simple sentences negative, use did not or the contraction didn't. After didn't, use the base form of the main verb. For example, She didn't come is correct. She didn't came is incorrect because didn't already shows that the sentence is about the past. Questions with did For most yes-no questions in the past simple, put did before the subject and use the base form of the main verb: Did you see him? With a question word, use the same principle: Where did you go? Because did marks the past, the main verb does not use its irregular past form. When do we use these forms? Use the past simple for completed actions and events in the past. Time expressions such as yesterday, last night, last week, on Monday and two days ago often appear with this tense. A time expression is not always necessary when the past time is already clear from the context.

Core rules
- 1
Use the irregular past form in affirmative sentences
In an affirmative past simple sentence, an irregular verb uses its special past form: go → went, eat → ate and buy → bought.
- 2
The past form is the same for every subject
The irregular past form does not change with I, you, he, she, we or they. For example: I saw, she saw and they saw.
- 3
Use the base form after didn't
Didn't already marks the sentence as past, so the main verb returns to its base form: We didn't go, not We didn't went.
- 4
Use the base form after did in questions
When did is used to make a question, the main verb stays in its base form: Did she come? not Did she came?
- 5
Learn frequent irregular forms in context
There is no general -ed rule for irregular verbs. At A1 level, learn the most useful forms first and practise them in short, meaningful sentences.

Common mistakes
- ❌ I goed to school yesterday. ✅ I went to school yesterday. Go is irregular. Its past form is went, not goed.
- ❌ She eated breakfast at eight. ✅ She ate breakfast at eight. Eat does not form its past by adding -ed. Its past form is ate.
- ❌ We didn't went to the park. ✅ We didn't go to the park. After didn't, use the base form because didn't already marks the past.
- ❌ Did you saw him yesterday? ✅ Did you see him yesterday? After did, the main verb must be in the base form, so use see rather than saw.
- ❌ He buyed a new phone. ✅ He bought a new phone. Buy is irregular. Its past form is bought.
- ❌ Where did she went? ✅ Where did she go? In a past simple question with did, use the base form go.
Learning tips
- Learn irregular verbs as useful pairs, such as go → went and see → saw, and immediately use each pair in a short sentence.
- Start with high-frequency verbs such as go, come, see, eat, have, get, make, take and buy instead of trying to memorize a very long list.
- In affirmative sentences, check the irregular past form. After did or didn't, check that you have used the base form.
- Words and phrases such as yesterday, last night, last week and two days ago often help you recognize a past context.
- Practise irregular verbs in small groups and everyday situations so that you learn how to use them, not only how to recognize them.

Frequently asked questions
Why do we say went instead of goed?
Go is an irregular verb, so it does not form the past simple by adding -ed. Its past form is went.
Do I need to memorize all irregular verbs at once?
No. At A1 level, start with common verbs that you need in everyday communication. Learn a small group, use them in sentences, and gradually add more.
Why do we say I didn't go instead of I didn't went?
Didn't already contains the past form did. Because the past is marked by didn't, the main verb uses its base form: go.
Why is Did you see correct and Did you saw incorrect?
Did already marks the question as past. The main verb therefore stays in its base form, so see is correct.
How can I know if a verb is irregular?
There is no single reliable rule that identifies every irregular verb. You need to learn the common irregular forms individually, preferably with examples and regular practice.
Does the past form change with he, she or it?
No. The past simple form is the same for all subjects. For example, we say I went, she went and they went.
