100+ Most Common English Irregular Verbs: Past Simple and Past Participle

Irregular verbs appear constantly in spoken and written English. We say went, not goed, and written, not writed. That is why a reliable irregular verbs list is useful at every level, from the first past simple lesson to advanced writing.

What are irregular verbs?

A regular verb follows a predictable rule. For example, work becomes worked, while start becomes started. An irregular verb changes in another way, or sometimes does not change at all.

• Complete change: go, went, gone
• Vowel change: sing, sang, sung
• Same past simple and past participle: build, built, built
• No visible change: cut, cut, cut

Many of the most frequent verbs in English are irregular, including be, have, do, say, make, go, take, come, see and get. Therefore, learning these forms improves conversation, listening, reading and writing at the same time.

Why does English have regular and irregular verbs?

To understand irregular verbs, it helps to look briefly at regular verbs. Most English verbs form the past simple and past participle with the productive -ed pattern. For example, work becomes worked, play becomes played and want becomes wanted. This rule also applies to new verbs that enter the language, which is one reason it is so powerful.

A short history of strong and weak verbs

Modern irregular verbs are not random mistakes. Many are survivors of a much older system inherited from the Germanic history of English. In Old English, verbs were commonly divided into strong verbs and weak verbs. Strong verbs often marked the past by changing a vowel inside the verb, a process that can still be seen in sing, sang, sung and write, wrote, written. Weak verbs used an ending containing a d or t sound. That dental ending is the historical ancestor of the modern -ed pattern.

Therefore, it is not quite accurate to say that every verb was once irregular in the modern sense. Old English already had both strong and weak verbs. However, the strong class was considerably larger, and many verbs that once changed internally later adopted the more productive weak pattern. In other words, the irregular list has been reduced over the centuries.

A study published in Nature followed 177 verbs that were irregular in Old English. Of those verbs, 145 were still irregular in Middle English, while 98 remained irregular in Modern English. Verbs such as help, laugh, reach, walk and work moved towards regular forms. This historical process is called regularisation.

Dreamed and dreamt show language change in progress

The verb dream is an excellent example because two histories are visible at the same time. The forms dreamed and dreamt are both correct. Dreamed follows the regular -ed pattern, while dreamt preserves an irregular form. Dreamed is particularly dominant in American English and is also used in British English. Dreamt remains especially familiar in British English. Therefore, this is a difference in preference, not a rigid border between two completely separate systems.

The same kind of variation appears in pairs such as learned/learnt and burned/burnt. These pairs allow us to observe how regular and irregular forms can coexist for generations before one becomes more frequent, both remain stable or usage changes direction again.

Will every irregular verb eventually become regular?

It is possible that future generations will use fewer of the irregular forms we know today. Our great-great-grandchildren may learn a slightly different list, and speakers living one or two thousand years from now may use forms that sound unusual to us. However, no one can responsibly set a date when every English verb will become regular.

Frequency is one important reason. The most common irregular verbs are repeated so often that their forms remain strongly established. The Nature study estimated extremely long historical half-lives for verbs such as be and think. Moreover, language does not move in only one direction. The regular past sneaked, for example, later developed the irregular alternative snuck. English can regularise old forms, but speakers can also create or strengthen new irregular patterns.

Therefore, a future English with fewer irregular verbs is plausible, but a future with none is not something the evidence allows us to promise. Perhaps our distant descendants will settle that question. For learners living now, however, waiting a few centuries is not a useful study plan.

Patterns that make irregular verbs easier to remember

Irregular does not always mean completely random. Several useful groups repeat the same type of change. Learning these groups is usually more effective than memorising a long list without connections.

British and American irregular verb forms

Some verbs have two accepted forms. One may be more common in British English, while another may be more common in American English. Both can be correct, although consistency is important in formal writing.

Common mistakes with irregular verbs

Using the past simple after have, has or had

Do not say I have went. After have, has or had, use the past participle.

Incorrect: I have went there twice.
Correct: I have gone there twice.

Using the past participle alone as the past simple

The past participle normally needs an auxiliary verb. Therefore, She written yesterday is incomplete.

Incorrect: She written the report yesterday.
Correct: She wrote the report yesterday.
Also correct: She has written the report.

Adding -ed to an irregular form

Forms such as goed, buyed and teached are common learner errors because they apply the regular rule to irregular verbs.

Correct forms: went, bought and taught.

Confusing lie and lay

Lie means to rest in a horizontal position: lie, lay, lain. Lay means to put something down: lay, laid, laid.

Yesterday, I lay on the sofa. Then I laid my phone on the table.

How should you learn irregular verbs?

Begin with the forms you hear and use most frequently. Study a small group, notice the pattern and create a sentence connected to your own life. In addition, alternate recognition with production. First, identify the correct form while reading. Then close the list and produce the three forms aloud.

For example, instead of repeating only take, took, taken, connect the forms to real messages:

• I take the bus every morning.
• I took a taxi yesterday.
• I have taken this route many times.

This approach helps you understand not only what the forms are, but also when each form is needed.

Frequently asked questions

How many irregular verbs are there in English?

The exact number depends on whether rare, archaic, regional and prefixed forms are included. For practical communication, learners normally focus on roughly 100 to 200 common irregular verbs.

What is the difference between the past simple and past participle?

The past simple can normally form the main verb of a completed past action. The past participle is used with auxiliary verbs in perfect tenses and passive structures.

Is gotten correct English?

Yes. Gotten is widely used as a past participle in American English. In British English, got is normally preferred, except in a few fixed expressions.

Are burnt, dreamt and learnt correct?

Yes. These forms are standard, particularly in British English. The forms burned, dreamed and learned are also correct and are especially common in American English.

Why do some irregular verbs have the same three forms?

Historical sound changes produced different patterns. Some verbs kept one unchanged form, such as cut, cut, cut, while others preserved vowel changes, such as sing, sang, sung.

Reference checking: verb forms, historical development and accepted variants were checked against established references, including EnglishClub, Gallaudet University, Cambridge Dictionary, The Cambridge Handbook of Germanic Linguistics, the historical regularisation study published in Nature and Merriam-Webster’s usage history of dreamed and dreamt.
