Commit or Comit: Which Is Correct?

Updated 2026-10-12 · Which One Is Correct editorial team

Quick answer: When you ask whether to write commit or comit, the correct choice is always commit. The spelling comit is incorrect and should be avoided in all formal and informal writing. This common error often happens because the word looks similar to other terms like comitatus or because the double t is overlooked. Knowing the difference ensures your writing remains clear and professional. Use the correct form to maintain accuracy.

The Short Answer

commit is the correct spelling, while comit is a misspelling that you should never use in standard English.

People often confuse these words because they sound identical when spoken, and the double t is easy to miss if you are typing quickly. Additionally, the root of the word relates to Latin forms that might lead to confusion, but English spelling rules require the extra t for this specific verb.

Frequently Asked Questions

Why do people write comit instead of commit?

People often write comit because they hear the word and assume the spelling follows the sound exactly, forgetting that English spelling often includes silent letters or double letters. This error is very common because the double t is not emphasized in pronunciation.

Is comit ever correct in any English context?

No, comit is never correct in modern standard English. It is strictly a misspelling of the verb commit, and using it will be considered an error in any professional or academic setting. Always use the double t to ensure accuracy.

What is the past tense of commit?

The past tense of commit is committed, which adds an extra d to the end. The spelling of the base word remains commit with the double t, so the past form becomes committed to maintain the root structure.

How do I remember the correct spelling?

You can remember the spelling by associating it with the noun commitment. Since the noun has two t's, the verb commit must also have two t's to match the root. Thinking about the noun form helps lock the correct spelling into your memory.
