What are common irregular verbs in English and their forms

Common irregular verbs in English do not follow the regular pattern of adding -ed for the past simple and past participle. Instead, they change form in ways that must be learned individually, although many of the most common ones are used constantly in everyday speech.

Here are some common irregular verbs with their base form, past simple, and past participle forms:

Base Form	Past Simple	Past Participle
be	was/were	been
become	became	become
begin	began	begun
break	broke	broken
bring	brought	brought
buy	bought	bought
catch	caught	caught
come	came	come
do	did	done
drink	drank	drunk
drive	drove	driven
eat	ate	eaten
fall	fell	fallen
feel	felt	felt
find	found	found
get	got	gotten/got
give	gave	given
go	went	gone
have	had	had
hear	heard	heard
keep	kept	kept
know	knew	known
leave	left	left
lose	lost	lost
make	made	made
meet	met	met
pay	paid	paid
put	put	put
read	read	read
run	ran	run
say	said	said
see	saw	seen
sell	sold	sold

teach	taught	taught
tell	told	told
think	thought	thought
understand	understood	understood
wear	wore	worn

Why irregular verbs matter

These verbs are among the most frequent in English, which is why they matter so much for conversation, listening, and reading. Words like go, have, do, get, make, say, see, take, come, and know appear constantly in daily English, and mistakes in their forms are immediately noticeable.

Irregular verbs are especially important because English uses them in two very common places:

• Past simple: for finished actions, as in I went home early.
• Past participle: in perfect tenses and passive structures, as in I have gone home or The book was written in 1950.

Common patterns in irregular verbs

Even though irregular verbs do not follow one single rule, many of them are not completely random. A few useful patterns appear again and again.

1. All three forms are the same

Some verbs keep the same form in the base form, past simple, and past participle:

• put – put – put
• read – read – read
• cut – cut – cut
• hit – hit – hit
• set – set – set

These are often easier to remember because no spelling change is needed, but pronunciation can still change. For example, read is pronounced like reed in the base form, but like red in the past forms.

2. The vowel changes

Many common verbs change only the vowel sound and spelling:

• begin – began – begun
• drink – drank – drunk
• sing – sang – sung
• swim – swam – swum
• write – wrote – written

This pattern is common in older English verbs and is one reason irregular forms often look historically related even when they feel unpredictable.

3. The past simple and past participle are the same

A large group of verbs uses one form for both the past simple and past participle:

• bring – brought – brought
• buy – bought – bought
• catch – caught – caught
• feel – felt – felt
• keep – kept – kept
• lose – lost – lost
• say – said – said
• teach – taught – taught
• think – thought – thought

This group is useful because once the past simple is learned, the past participle is already known.

A few especially common trouble spots

Be

The verb be is the most irregular English verb and the most important one to master.

• I am / was / have been
• you are / were / have been
• he, she, it is / was / has been
• we, you, they are / were / have been

It behaves differently from other verbs because it is used for identity, description, location, and as an auxiliary verb in continuous and passive forms.

Get

Get is especially interesting because both got and gotten appear in modern English. In British English, got is the standard past participle in most contexts. In American English, gotten is common when get means “obtain” or “become,” as in have gotten better or have gotten a ticket. In both varieties, got is still widely used in phrases such as have got meaning “have.”

Read

The spelling of read does not change across forms, but the pronunciation does.

• Present: read /riːd/
• Past simple and past participle: read /red/

This makes read a frequent source of listening and pronunciation confusion.

How to learn irregular verbs efficiently

The most effective way to learn irregular verbs is to group them by pattern instead of memorizing a long random list. Verbs that rhyme or share a form are easier to retain:

• sing – sang – sung
• ring – rang – rung
• drink – drank – drunk
• swim – swam – swum

Short example sentences also help because they show how the form works in context:

• Yesterday I went to the store.
• She has gone home already.
• We took the train.
• They have taken the bus many times.

Active use matters as much as recognition. Repeated speaking practice, especially in short real-life sentences, helps irregular forms become automatic more quickly than passive review alone.

These verbs are important to memorize because their forms are not predictable by simple rules. ^{1, 11}
