50 irregular verbs present past and past participle forms are the core list every English learner needs, because these verbs refuse the simple -ed rule. The base form changes inside the word: go becomes went and then gone, while cut stays cut in all three slots.
Irregular verbs at a glance
- Irregular verbs form the past tense and past participle without adding -ed.
- The base form is the plain verb, as in go, sing and write.
- The past tense names an action that already finished.
- The past participle follows have, has or had and also forms the passive.
- Some irregular verbs keep one form throughout, as in cut, cut, cut.
- Others change all three slots, as in sing, sang, sung.
What is an irregular verb?
An irregular verb is a verb whose past tense and past participle do not follow the regular -ed pattern. English keeps about two hundred of them, and fifty cover most of what you read and say. They show up constantly in sentences about the past, so learning the top group first pays off quickly.
| Principal part | What it shows | Example |
|---|---|---|
| Base form | The plain verb, used for the present and after to | They write a report each week. |
| Past tense | A finished action with no helper verb | They wrote a report yesterday. |
| Past participle | The form used after have and in the passive | They have written the report. |
| No-change group | One form serves all three slots | We cut the paper, and we have cut it. |
The final column names the reason the form is correct; for more frames about finished time, read sentences about the past.
How do you form the past tense and past participle?
The helper word decides which form appears. After have, has or had, use the past participle; after did or did not, drop back to the base form. Once the helper is fixed, the verb form follows automatically.
| Pattern | Example | What it signals |
|---|---|---|
| have / has / had + past participle | She has chosen a new topic. | The action is complete at the moment of speaking. |
| be + past participle | The window was broken by the wind. | The doer is unknown or unimportant. |
| base form after did | He did not go to the shop. | The past is already marked, so the verb stays plain. |
| to + base form | I want to swim after lunch. | The infinitive never takes the past form. |
| will + base form | They will meet us later. | A future helper also keeps the verb plain. |
The same older vowel pattern appears in irregular adjective comparisons, where a handful of common words break the standard rule.
50 irregular verbs in sentences across contexts
Each line below uses a different verb and a different register, from a chatty note to a lab report. The final column names the reason the form is correct. For more frames about finished time, read sentences about the past.
| Context | Example sentence | Why this works |
|---|---|---|
| Everyday speech | I ate breakfast before school. | ate is the past of eat and needs no helper. |
| Classroom writing | The teacher has taken our notebooks home. | has plus taken shows a finished action that still matters. |
| Work email | We sent the invoice on Monday. | sent keeps the message short and clear. |
| News report | The team won three games last season. | won marks a completed event with a time reference. |
| Story telling | She sang a quiet song to the baby. | sang is the past form for one finished action. |
| Technical writing | The pipe burst under pressure. | burst stays the same in all three forms. |
| Travel diary | We flew to Rome and saw the walls. | flew and saw are both past forms. |
| Academic essay | The study found that children learned faster. | found and learned are both past forms. |
| Instruction manual | Switch off the machine once it has stopped. | has plus stopped follows a time clause. |
| Exam practice | She drew a map before the test. | drew is the past of draw. |
| Correspondence | We began the meeting at nine. | began is the past of begin. |
The base form sits in present-tense sentences and returns whenever a helper such as did carries the past.
Irregular verbs vs regular verbs
The contrast explains why the list must be learned verb by verb. A regular verb follows one rule; an irregular verb keeps an older vowel pattern that has to be memorised. The same idea appears in irregular adjective comparisons, where a handful of common words break the standard rule.
| Feature | Irregular verbs | Regular verbs |
|---|---|---|
| Past tense | Change their vowel or stay the same, as in sing, sang | Add -ed, as in walk, walked |
| Past participle | Often a third form, as in sung | Same as the past, as in walked |
| Number of patterns | Many, learned one by one | One rule for almost every verb |
| Common example | go, went, gone | play, played, played |
| Learning tip | Group by sound, as in sing, sang, sung | Add -ed and check the spelling rule |
| Mistake risk | High, because the vowel changes | Low, though doubled letters trip writers |
Verb forms and grammar of irregular verbs
Every English verb carries five common forms, and the irregular ones simply fill those slots differently. The table keeps the labels in one place so the same word can be recognised in each role. The final row names a plain verb used as a label, one of many verbs used as descriptors.
| Form | Part of speech | Example |
|---|---|---|
| base (go) | verb | They go home at five. |
| third person singular (goes) | verb | She goes home at five. |
| past (went) | verb | They went home at five. |
| past participle (gone) | verb | They have gone home. |
| present participle (going) | verb | They are going home. |
| noun labelling a turn (a go) | noun | We had a go at the puzzle. |
The final row names a plain verb used as a label, one of many verbs used as descriptors.
Register decides how strict you must be with these forms. Many speakers say I have went in relaxed conversation, but that form reads as an error the moment it reaches the page, so keep the participle after have, has and had. Rhythm offers a second clue: the no-change verbs such as cut, put and set carry no sound difference between the tenses, so the other words in the sentence must show the time. Reading each line aloud catches a missing participle faster than checking a rule, because the ear notices the gap before the eye does. Treat this table as the high-frequency core rather than a closed set, since the full inventory of irregular verbs reaches roughly two hundred.
Common mistakes with irregular verbs
- Incorrect:
She has went home.Correct: She has gone home. Rule: after have, has or had use the past participle, not the past form. - Incorrect:
He did not went.Correct: He did not go. Rule: after did, the verb returns to the base form. - Incorrect:
I have ate lunch.Correct: I have eaten lunch. Rule: eat has the participle eaten. - Incorrect:
They have wrote the letter.Correct: They have written the letter. Rule: write keeps the -en participle. - Incorrect:
The bell has rang.Correct: The bell has rung. Rule: ring is rang in the past and rung in the participle. - Incorrect:
We have drank the water.Correct: We have drunk the water. Rule: drink has the participle drunk.
Practice using irregular verbs
- Fill the gap: She has ______ all the juice. (drink)
- Fill the gap: The children ______ to the gate yesterday. (run, past)
- Choose the correct form: We have (took / taken) the early train.
- Correct the error: He has saw the film twice.
- Build a sentence using have plus the past participle of break about a window.
- Spot the register: which line belongs in a lab report, (a) The sample froze overnight, or (b) The sample has frozed overnight?
Answers
- drunk, because after has the verb takes the participle drunk.
- ran, because yesterday needs the past form ran, not the participle.
- taken, because after have we use the past participle taken.
- He has seen the film twice, because see has the participle seen.
- The window has been broken, because have plus the participle forms the passive.
- (a) The sample froze overnight, because it is the plain past and frozed is not a word.
The bottom line
The 50 irregular verbs present past and past participle forms in this table cover the verbs you meet most often. Learn them in vowel families such as sing, sang, sung rather than as a flat list, and read them aloud so the sound fixes the shape. One rule removes most errors: after have comes the participle, and after did the verb stays plain.
Frequently asked questions about irregular verbs
How many irregular verbs does English have?
English has roughly two hundred irregular verbs, and about fifty appear in everyday speech. The fifty in the table above cover the verbs you meet most often in reading, writing and conversation, so learning them first gives the largest gain for the least effort.
Why do irregular verbs change their vowels?
Most irregular verbs come from the older Germanic stock of English, where a vowel change marked the past. That pattern survived in high-frequency verbs such as sing, sang, sung, while thousands of newer or rarer verbs took the regular -ed ending instead.
Which irregular verbs stay the same in all three forms?
A small group keeps one form for the base, the past and the participle. Cut, put, set, let and hit never change, so you judge the tense from the other words in the sentence, as in I cut it yesterday or I have cut it already.
Is the past participle always different from the past tense?
Often the two forms differ, as in sang and sung, but not always. Some verbs share the past and participle, such as buy, bought, bought, and the no-change group shares all three, so the participle is learned alongside the past.
