English has about 200 irregular verbs — verbs that don't follow the standard "-ed" past tense pattern. The good news? You only need about 50-70 for everyday conversation, and they fall into predictable PATTERN GROUPS.
The 5 Main Pattern Groups

| shut | shut | shut |
| cost | cost | cost |
| hit | hit | hit |
Group 2: Vowel Change (ABB pattern)

Learning verbs by pattern group is 3× more effective than random lists. Your brain spots the pattern and applies it to new verbs automatically.

How many irregular verbs are there in English?
There are roughly 200 irregular verbs, but only about 50-70 are truly common in everyday speech. Focus on the high-frequency ones first (be, have, go, get, make, take, see, come) and you will cover the vast majority of what you actually use.
What is the best way to memorise irregular verbs?
Group them by pattern rather than learning them alphabetically. Many share the same vowel change (sing-sang-sung, ring-rang-rung; drive-drove-driven, ride-rode-ridden). Learning them in families plus spaced repetition of full sentences makes them stick far faster.
Do I need to learn all three forms of each verb?
Yes — the base, past simple and past participle. The past simple is used for finished actions (I saw it) and the past participle for perfect tenses and the passive (I have seen it). Always learn the three forms together as a set.
Learn irregular verbs in sound-pattern families, always as all three forms, and review them inside real sentences with spaced repetition.
