Submission or Submittion: Which Is Correct?
Updated · Which One Is Correct editorial team

Quick answer: The correct spelling is always submission, while submittion is a frequent misspelling. This error often occurs because the word contains two t's, tempting writers to double it again. Understanding the root verb helps clarify the proper form for all contexts. This guide provides a clear verdict to help you write with confidence.
The Short Answer
submission is the correct spelling; submittion is a misspelling that should be avoided in all writing. The root verb is submit, and adding the suffix -ion creates the noun submission with a single t before the suffix begins.
People often confuse these words because the verb submit contains a double t, which can create a mental expectation of two t's in the derived noun. However, English spelling rules do not require doubling consonants when adding suffixes that begin with vowels unless the base word ends in a single vowel followed by a single consonant. In this case, the doubling does not apply, leading to the common mistake.

A Quick Test You Can Use
To ensure you use the right word, check if the sentence describes an act of giving something over or yielding to authority. If the meaning fits, use submission. Remember that the base verb submit has two t's, but the noun form only keeps one because the suffix starts with an i, which changes the doubling rule.

Frequently Asked Questions
Why do people spell it submittion?
People spell it submittion because they see two t's in the verb submit and incorrectly assume the noun should also have two. This is a common error because the rule for doubling consonants does not apply when adding the -ion suffix.
Is there any context where submittion is okay?
No, there is no context where submittion is acceptable. It is always a misspelling, and using it will make your writing look unprofessional or contain a clear error in standard English.
What is the difference between the noun and verb?
The verb submit means to give something to someone or yield to authority, while the noun submission refers to the act of doing so or the state of yielding. The verb keeps the double t, but the noun uses only one.
How do I remember the correct spelling?
You can remember the correct spelling by thinking of the phrase 'one t in the noun.' Since the suffix starts with i, the final t of the root word remains single. Visualizing the word with just one t helps prevent the mistake.
