Begun or Began: The Simple Guide to Using These Verbs Correctly

Many English learners and even native speakers search for “begun or began” because these two words look similar but work very differently in sentences.

Both come from the same verb, begin, yet they are not interchangeable. Using the wrong one can make your writing sound incorrect or unprofessional, especially in emails, exams, blogs, or formal documents.

Because English relies heavily on verb structure, a small mistake here can change the meaning of a sentence.

This article solves that confusion step by step. You will get a quick answer, clear examples, common mistakes, and practical advice on which form to use and when.

By the end, you will confidently know whether begun or began is correct in any situation—without overthinking it.
