Most common irregular verbs and their past forms
Here is a list of some of the most common English irregular verbs along with their past tense and past participle forms:
| Base Form | Past Tense | Past Participle |
|---|---|---|
| be | was/were | been |
| have | had | had |
| do | did | done |
| go | went | gone |
| say | said | said |
| see | saw | seen |
| get | got | got/gotten |
| make | made | made |
| know | knew | known |
| think | thought | thought |
| take | took | taken |
| come | came | come |
| want | wanted¹ | wanted¹ |
| look | looked¹ | looked¹ |
Note: Some verbs like “want” and “look” are actually regular, so they have -ed endings, just included here for context.
These verbs are irregular because they do not form their past tense or past participle by simply adding -ed.
This selection includes verbs frequently used in English. There are more irregular verbs, some with multiple past participle forms (like “got” or “gotten”).
Understanding Irregular Verbs: Why Are They Different?
Irregular verbs break the usual pattern of simply adding -ed to the base form for past tense and past participle because they have evolved from different origins in Old English or other Germanic languages. This historical development means their forms often change completely or change vowel sounds internally, instead of following the predictable pattern of regular verbs.
For example, the verb go forms its past tense as went, which originally was the past tense of a different verb, wend. This irregular inheritance adds complexity but also reflects the richness of the language’s history.
Patterns Among Irregular Verbs
While irregular verbs may look random at first, many follow patterns that can help learners recognize and memorize their forms. Here are some common patterns:
-
Vowel changes (ablaut): Many verbs change their internal vowel when forming past tense and past participle.
Examples:
- sing – sang – sung
- drink – drank – drunk
- begin – began – begun
-
No change in past participle: Some verbs have the same past tense and past participle form.
Examples:
- put – put – put
- cut – cut – cut
- hit – hit – hit
-
Double forms: A few verbs have two acceptable past participle forms, often with different registers or regions.
Example:
- get – got – got/gotten (Gotten is more common in American English, while British English prefers got)
Understanding these patterns can make irregular verbs less intimidating and more approachable for conversation practice.
Common Usage Examples in Conversation
Using irregular verbs fluently often depends on mastering not only the form but also the appropriate context and pronunciation. Here are some practical examples for speakers:
-
Be:
“I was at the café yesterday.” (Past tense)
“I have been busy all week.” (Past participle with present perfect) -
Have:
“She had a great time at the party."
"They have had enough food.” -
Go:
“We went to the museum last Sunday."
"He has gone home for the day.” (Note difference between past tense and past participle indicating action still relevant) -
Say:
“She said she would call later."
"Have you said hello to him yet?” -
Know:
“I knew the answer immediately."
"Have you known him long?”
Pronunciation can be a common challenge, particularly with past tense and past participle endings. For example, the “-ed” ending often blends into the final sound but must be clear enough to be understood. Active speaking practice helps develop natural use and pronunciation.
Common Mistakes with Irregular Verbs
-
Using the regular -ed ending with an irregular verb:
Saying “goed” instead of “went” or “buyed” instead of “bought” is a frequent error among learners. This occurs when learners apply the default rule but ignore the irregular form. -
Confusing past tense and past participle forms:
For example, using “I have went” instead of “I have gone”. Because the past participle is used with perfect tenses, mixing these forms can lead to ungrammatical sentences. -
Mispronouncing irregular past participles:
Some irregular past participles end differently from the past tense forms or have silent letters, such as “known”. Careful listening and practice with native speakers or conversation tutors can improve accuracy.
Tips for Mastery
-
Focus on the most frequent verbs first: The 20 most common irregular verbs cover a large portion of everyday conversation. Prioritizing these creates a solid foundation.
-
Group learning by patterns: Recognizing vowel changes or other patterns can speed memorization.
-
Practice in context: Rather than rote memorization, applying verbs in real sentences and conversations improves retention.
-
Use spoken drills: Since irregular verbs often appear in conversation, practicing speaking (especially with feedback) is notably more effective than only reading or writing.
Brief FAQ
Q: Are irregular verbs more common in spoken or written English?
A: Irregular verbs appear frequently in both, but spoken English especially relies on them for everyday verbs like be, have, go, and do. Mastery improves fluency significantly.
Q: Can irregular verbs become regular over time?
A: Yes, language evolves and some irregular verbs become “regularized.” For example, “help” was once irregular but is now regular. However, the most common irregular verbs tend to resist this change.
Q: Is “gotten” incorrect in standard English?
A: “Gotten” is standard in American English as the past participle of “get,” while British English usually prefers “got.” Both are correct but usage varies by region.
