Every English learner hits the same wall. You learn the rule — add -ed for the past — and it works beautifully: walk, walked; play, played. Then you meet go and the past is went. Then think becomes thought, put stays put, and somewhere around buy → bought the list starts to feel like pure chaos you're supposed to memorize one verb at a time.
Here's the good news: it isn't chaos. English has roughly 200 irregular verbs in everyday use, and most of them fall into a handful of sound patterns. Learn the patterns and the list shrinks from 200 random facts to about seven families plus a few loners.
The ten most frequent verbs in English — be, have, do, say, go, get, make, know, think, take — all irregular. You can't postpone irregular verbs; they run the language.
Why English has irregular verbs at all
Old English, like modern German, had "strong" verbs that marked tense by changing the vowel inside the word — a system called ablaut. Sing, sang, sung is a thousand-year-old vowel alternation, not a mistake that stuck.
Over the centuries most verbs migrated to the regular -ed pattern. The ones that survived are the ones used so often that every generation heard the old forms constantly: helped replaced holp, but nobody ever got the chance to forget went. That's why the irregular list reads like a frequency list of English itself — and why rare verbs are almost always regular. Frequency preserves irregularity.
The 20 irregular verbs to learn first
If you're starting out, don't touch an alphabetical table. Learn these first — they're the highest-frequency verbs in the language, and you'll meet them in almost every sentence:
| Base | Past simple | Past participle |
|---|---|---|
| be | was / were | been |
| have | had | had |
| do | did | done |
| say | said | said |
| go | went | gone |
| get | got | got / gotten |
| make | made | made |
| know | knew | known |
| think | thought | thought |
| take | took | taken |
| see | saw | seen |
| come | came | come |
| find | found | found |
| give | gave | given |
| tell | told | told |
| become | became | become |
| leave | left | left |
| feel | felt | felt |
| put | put | put |
| bring | brought | brought |
Master these 20 and you've covered a huge share of the irregular forms you'll actually hear and need.
Seven patterns that cover most of the list
Once the top 20 are solid, stop learning verbs one by one. Group them:
| Pattern | Model verb | Others in the family |
|---|---|---|
| Nothing changes | put – put – put | cut, cost, hit, hurt, let, set, shut |
| -ought / -aught | think – thought – thought | buy, bring, catch, teach, fight, seek |
| Short vowel + -t | keep – kept – kept | sleep, feel, leave, mean, meet, lose |
| i → a → u | begin – began – begun | drink, sing, swim, ring, sink |
| -ew → -own | know – knew – known | grow, throw, blow, fly (flew, flown) |
| Past = participle, new vowel | find – found – found | sit (sat), win (won), stand (stood), get (got), hear (heard), sell (sold), tell (told) |
| Participle in -en | speak – spoke – spoken | write, break, choose, drive, eat, fall, give, see, take |
Two things happen when you learn by family. First, each new verb costs less effort — throw is nearly free once you know know–knew–known. Second, your brain starts predicting: meet a new verb like sink and the form sank, sunk already sounds right.
Learn all three forms as one chunk
The most common study mistake is learning the base form now and "the past tense later". Later never comes cheap: you end up knowing speak but freezing on spoken.
Treat the triple as a single vocabulary item. Your flashcard isn't go — it's go – went – gone, spoken aloud with rhythm, like a tiny chant. When the card comes up, you must recall all three forms, not just recognize them. Recall is what builds the automatic reflex you need mid-sentence, and it's the mechanism that makes spaced repetition so effective for exactly this kind of material: small, discrete facts that fade fast without review — the classic victims of the forgetting curve.
A 10-minute daily drill
- Review first (4 min). Clear whatever verb cards your spaced-repetition schedule says are due. This step is non-negotiable — it's what keeps thought and taught from blurring back together.
- Add one family (4 min). Introduce 4–6 new verbs from the same pattern group, never an alphabetical slice. Say each triple aloud.
- Spell it (2 min). Irregular pasts are also spelling traps — caught, bought, written. A quick round of a typing or hangman-style game locks the spelling in without feeling like study.
Ten minutes daily beats an hour on Sunday, because the forms you don't revisit are precisely the ones that vanish. LexiNest's free English course schedules those reviews for you and orders vocabulary by frequency, so the verbs you drill first are the ones you'll actually use.
The mistakes to expect (and why they're good signs)
"I goed", "she buyed." Every learner produces these — so does every native-speaking child around age three. It's called overregularization, and it means your brain has correctly learned the -ed rule and is applying it everywhere. You're not failing; you're one exceptions-list away from correct.
"I have went." Mixing the past simple and the participle is the classic intermediate error. The fix is mechanical: after have/has/had, always the third column. If you've been drilling triples as chunks, the right form is already in the chant — go, went, gone.
Trusting your ear too early. Burned or burnt? Dreamed or dreamt? Some verbs are mid-migration to regularity and both forms are fine. Don't let the wobbly edge cases distract you from the stable core in the tables above.
Frequently asked questions
How many irregular verbs does English have?
Around 200 are in everyday use (larger lists count archaic ones like smite). But frequency is wildly skewed: the top 50 irregular verbs account for the overwhelming majority of real-world usage. Learn those 50 well and the rest are a slow, low-pressure mop-up.
Is it "got" or "gotten"?
Both. British English uses got as the participle (I've got), American English generally uses gotten (I've gotten). Pick the variety you're learning and be consistent — neither is wrong.
Should I learn irregular verbs in alphabetical order?
No. Alphabetical tables put become next to begin — different patterns, similar spellings, maximum confusion. Learn by frequency first (the top 20 above), then by pattern family, and let a spaced-repetition schedule decide when each verb comes back.
Do new English verbs become irregular?
No — every new verb entering English is regular (googled, texted, streamed), and existing irregulars slowly drift toward regularity, not away from it. The irregular list is a closed, shrinking club. That's genuinely comforting: what you memorize today is the hardest it will ever be.
