Irregular verbs can be sorted into groups by pattern, but the patterns don’t help you remember the forms. For the most part, these need to be memorized. Most people memorize them simply by hearing them, reading them, or being corrected.

The patterns are:

  1. present, past, and past participle are the same. (put/put/put)
  2. past and past participle are the same (catch/caught/caught)
  3. past + n or en forms past participle (freeze/froze/frozen)
  4. present + n/en/ne forms past participle (do/did/done)
  5. final vowel changes from i in present to a in past to u in past participle. (begin/began/begun)


If you aren’t sure, look up the verb in the dictionary. If the verb is irregular, the dictionary will give you the past and past participle form.
