Is it began or begun? That’s a good question and one I hear all the time. Both words are correct forms of the verb begin, which means their definition is the same. But they have a massive difference in terms of usage. Learn the difference between begun and began in this guide with writing tips.

Begun vs. Began

Both began and begun are correct. No word is incorrectly spelled. However, their usage differs.

Both begun and began are the past tense forms of an irregular action verb begin. An irregular verb is a verb that does not follow the typical pattern of its past form. That means it does not end in -d or -ed, as in begined.

Begin means to start, undergo, or perform.

  • Began is a simple past tense of begin. It does not need a helping verb.

Example: I began drinking coffee at 7 AM.

  • Begun is the past participle of begin. We use it with helping verbs like have, has, or had to form perfect tenses. Sometimes, we use it as an adjective for modifying a noun or pronoun.

Example: We’ve only just begun eating dinner.
