Irregular Verbs: Master 50+ Forms with Examples & Conjugation Tables

The first time I taught irregular verbs, I made a rookie mistake: I assigned a list of 200 verbs to memorise. The students panicked. A decade later, I realised that irregular verbs aren’t the problem — the approach is. Most English learners will never need all 200. What they need are the 50 most common irregular verbs, used repeatedly in conversation and writing, plus the patterns that make the rare ones easier to guess. I focus on the ones that actually matter, the patterns you’ll recognise, and the memory tricks my students have found most useful.

Whether you’re struggling with “went” vs. “go,” confused by past participles, or trying to understand why English has so many exceptions to its own rules, You’ll gives you the conjugation tables, real examples in context, and the mistakes you need to avoid.

What Are Irregular Verbs?

Definition: Irregular verbs are verbs that do not follow the standard pattern of adding –ed to the base form to create the past tense and past participle. Instead, they have unique, unpredictable forms that must be memorised.

English has about 200 irregular verbs, but only about 50 are commonly used. The rest are archaic, rare, or restricted to specific contexts. This guide focuses on the essential 50 that appear in everyday conversation, writing, and exams.

Contrast:

Regular verb: walk → walked → walked (all three forms follow the –ed pattern)

Irregular verb: go → went → gone (each form is unique; no –ed added)

The Three Forms of Irregular Verbs

Every verb in English has three core forms used to express all tenses:

1. Base Form 🔊 🎤 — used in the present tense with all pronouns except third person singular. Also used with modals (can, may, must, will, etc.).
2. Past Simple 🔊 🎤 — used to express completed actions in the past.
3. Past Participle 🔊 🎤 — used with auxiliary verbs to form perfect tenses (has/have/had + past participle), passive voice, and perfect continuous tenses.

50 Most Common Irregular Verbs

Irregular Verbs in Different Tenses

Past Simple (One-Time Completed Action)

Example 1: She went to the store yesterday.

Example 2: He ate breakfast before work this morning.

Example 3: They swam across the lake last summer.

Present Perfect (Action in Past with Present Relevance)

Example 1: I have been a teacher for fifteen years.

Example 2: She has gone to the doctor twice this month.

Example 3: They have eaten sushi for dinner already.

Past Perfect (Action Completed Before Another Past Action)

Example 1: By the time she arrived, I had already left.

Example 2: He had written the email before the meeting started.

Example 3: They had sung the song three times before the audience quieted down.

Future Perfect (Action Will Be Completed Before a Future Time)

Example 1: By next year, she will have graduated.

Example 2: He will have finished the project by Friday.

Example 3: They will have driven across the country by summer’s end.

Pattern Groups: Make Memorisation Easier

Some irregular verbs follow similar patterns. Grouping them together makes memorisation faster:

Anomalous Irregular Verbs

A few verbs are so irregular they don’t fit either strong or weak patterns. These are often the most common verbs in English, which makes sense — the verbs you use 100 times a day resist change.

Be: “am/is/are” – “was/were” – “been” (completely irregular in present tense)

Go: “go” – “went” – “gone” (past tense uses a completely different root, called “suppletion”)

Do: “do” – “did” – “done” (vowel change + consonant shift)

Have: “have” – “had” – “had” (vowel shortening)

Common Mistakes with Irregular Verbs

✗ Incorrect: She goed to the store.

✓ Correct: She went to the store.

Why: “Go” is irregular; never add –ed. The past simple is “went,” not “goed.”

✗ Incorrect: I have went to Paris three times.

✓ Correct: I have gone to Paris three times.

Why: Perfect tense requires the past participle, not past simple. “Gone” is correct; “went” is only for simple past.

✗ Incorrect: He drunk the water an hour ago.

✓ Correct: He drank the water an hour ago.

Why: Past simple uses “drank,” not “drunk.” “Drunk” is only the past participle, used with “has/have/had.”

✗ Incorrect: They builded a new house last year.

✓ Correct: They built a new house last year.

Why: “Build” is irregular; past simple is “built,” not “builded.”

✗ Incorrect: She has forgot her keys.

✓ Correct: She has forgotten her keys. (OR: She has forgot her keys — second version is increasingly accepted in American English, but “forgotten” is more formal.)

Why: Perfect tense with “have/has” requires the past participle “forgotten.” The form “forgot” is past simple, used for “She forgot her keys yesterday.”
