Commit vs Comit: Which Spelling Is Correct?

You are typing an email, and you pause. Is it “commit” vs “comit”? That one missing letter can make you look careless in a résumé, a report, or a text to your boss.

This guide settles the question. You will learn the right spelling, where the word comes from, why people get it wrong, and how to remember it for good. You will also find examples, grammar tables, and memory tricks you can use right away.

Commit vs Comit: The Quick Answer

“Commit” is the correct spelling. “Comit” is a misspelling.

Commit has two M’s and one T. Dropping an M gives you a word that does not exist in standard English.

Spelling	Correct?	Notes
Commit	✅ Yes	Standard English verb
Comit	❌ No	Typo or phonetic guess

Correct: She will commit to the project.
Incorrect: She will comit to the project.

Use two M’s every time, including in related forms like committed, committing, and commitment.

How to Pronounce Commit

Commit is pronounced kuh-MIT (/kəˈmɪt/). It has two syllables, and the stress falls on the second one.

Because the stress sits on “mit,” English doubles the final consonant when you add endings like -ed or -ing. That is why you get committed and committing. More on this rule below.

Where Does the Word Commit Come From?

Commit entered English in the late 1300s. It traces back through Old French to the Latin verb 

committere, 

which is built from two parts:

com- 

meaning “together” or “with”

mittere 

meaning “to send” or “to put”

So the original idea was “to bring together” or “to entrust something to someone.” That sense of handing something over still lives in modern phrases like “commit funds” or “commit it to memory.”

Why Do People Write “Comit”?

Mostly because the double M is silent in speech. You hear one “m” sound, so you write one. A few other habits make it worse, and they are covered in detail below.

What Does Commit Mean?

The word commit is a verb with several meanings depending on the context.

According to major dictionaries, commit means:

• To carry out an action.
• To pledge yourself to something.
• To entrust something to another person.
• To place information into memory.

Pronunciation

Say it slowly: kuh – MIT. Many learners find it helpful to say “kuh-mitt” with a crisp “t” at the end. The first vowel is soft, almost a grunt, which is also why people lose track of the spelling.

The Origin of the Word Commit

The Latin mittere is a busy root. It gave English dozens of words ending in -mit: submit, permit, admit, omit, transmit, remit, emit. Each one carries the idea of “sending” in a different direction.

Commit simply adds “com-” (together). Over centuries, the meaning stretched from “entrust” to “pledge” and eventually to “do” (as in commit a crime). Understanding this root helps with spelling too, since the mm comes from the prefix com- meeting the root mit.

Is Comit a Real Word?

No. “Comit” is not a standard English word and you will not find it as a regular entry in dictionaries like Merriam-Webster or Oxford.

You might spot “Comit” in other places:

As a brand, username, or company name

As a surname or place name in some regions

As the name of COMIT, an early string-processing programming language from the 1950s

None of those uses change the rule for everyday writing. If you mean the verb, spell it commit.

Why Do People Write “Comit”?

Spelling errors rarely come from laziness. They come from how our brains process words. Here are the three main reasons.

Double Letters Can Be Confusing

English is full of silent doubles. Words like accommodate, occurrence, committee, and embarrass trip up even confident writers. When a double letter does not change the sound, the brain tends to drop it.

Fast Typing

When you type quickly, your fingers can skip a repeated key, especially “m,” which sits at the end of the bottom row. Autocorrect catches many of these slips, but not always, especially in notes, search bars, and chat apps.

Pronunciation Doesn’t Help

Say “commit” out loud and you hear only one “m.” In “comet” or “comic,” the single “m” is correct. So the ear points you toward the wrong spelling. This is the biggest reason the error is so common.

Commit vs Comit: The Main Difference

Feature	Commit	Comit
Valid English word	Yes	No
Number of M’s	2	1
Part of speech	Verb (and noun in tech)	None
Appears in dictionaries	Yes	No
Past tense	Committed	N/A
Safe for formal writing	Yes	No

The difference is simple: one is a real word with a long history, and the other is a slip.

What Does Commit Mean in Different Situations?

Context decides which sense of “commit” you mean. Here are the four most common.

Commit an Action

This means to carry out or perform something, often something wrong or serious.

• He committed a foul in the final minute.
• Officials said the fraud was committed over several years.

Commit to a Goal

Here, commit means to dedicate yourself and follow through.

• I committed to running three times a week.
• The team is committed to launching by March.

Commit Information to Memory

This means to learn something so well you can recall it without notes.

• She committed the speech to memory in two days.
• Actors must commit their lines to memory before rehearsal.

Commit Resources

In business and government, commit means to set aside money, time, or people for a purpose.

• The company committed $2 million to research.
• The city has committed extra staff to the project.

Common Phrases That Use Commit

Some phrases appear again and again. Here are the ones worth knowing.

Commit a Crime

The most common legal use. The verb is always commit, not “do” or “make.”

• Police arrested him for committing a burglary.

Commit a Mistake

Slightly formal, but correct. In casual speech, “make a mistake” is more natural.

• The author committed several errors in the first draft.

Commit to a Relationship

Used for emotional or romantic pledges.

• After two years, they decided to commit to each other.

Commit to a Decision

Means sticking with a choice and not backing out.

• Once you commit to a decision, avoid second-guessing it daily.

Commit to Memory

Means memorizing something thoroughly.

• Students often commit formulas to memory before exams.

The Grammar of Commit

Commit is a regular verb with one spelling rule: double the final T before endings that start with a vowel.

Base Form

Commit:

 I commit to the plan.

Third-Person Singular

Commits:

 She commits every Sunday to meal prep. (No doubling, because “s” is not a vowel.)

Past Tense

Committed:

 They committed to the deal last week.

Present Participle

Committing: 

He is committing to a new routine.

Noun Form

The standard noun is commitment. In software, “commit” itself is also used as a noun.

• Her commitment to the cause was clear.
• I pushed a small commit to the repository.

Form	Spelling	Example
Base	commit	We commit to quality.
3rd person	commits	He commits to every deadline.
Past / past participle	committed	She committed early.
-ing form	committing	They are committing funds.
Noun	commitment	Their commitment is strong.

Word Family of Commit

Learning the family helps you spell all of them correctly, because they share the same double M.

Committed (adjective/verb):

 dedicated

Commitment (noun):

 a pledge or obligation

Committee (noun): 

a group assigned a task

Committal (noun): 

the act of sending someone to an institution

Committer (noun): 

one who commits, common in tech

Noncommittal (adjective): 

unwilling to take a position

Uncommitted (adjective):

 not dedicated or not yet assigned

Recommit (verb): 

to commit again

Notice that every one of them keeps mm. If you can spell committee or commitment, you can spell commit.

Why Does Commit Have Two M’s?

Two things come together here.

1. The prefix com- ends in “m.”
2. The root mit starts with “m.”

When they join, you get com + mit = commit. Nothing is dropped, so both M’s stay. This is how many English words with prefixes work. Think of immobile (in + mobile), unnatural (un + natural), and misspell (mis + spell).

The Rule Behind Double Consonants

When a verb ends in a single vowel + single consonant, and the stress falls on the last syllable, double the consonant before adding -ed or -ing.

Commit fits perfectly:

• Stress: kuh-MIT (last syllable)
• Ending: vowel (i) + consonant (t)
• Result: commit → committed, committing

Compare these:

Word	Stress	Doubles?	Result
commit	on last syllable	Yes	committed
permit	on last syllable	Yes	permitted
omit	on last syllable	Yes	omitted
visit	on first syllable	No	visited
limit	on first syllable	No	limited
edit	on first syllable	No	edited

If the stress is on the last syllable, double the last letter. If it is not, leave it alone.

Examples of Commit in Sentences

In Business

• Our leadership team committed to cutting delivery times by 20 percent.
• Investors are reluctant to commit capital without a clear plan.
• The firm is committed to transparent pricing.

In Education

• Teachers commit hours each week to lesson planning.
• She committed the periodic table to memory over the weekend.
• The school is committed to supporting every student.

In Personal Development

• Choose one habit and commit to it for thirty days.
• He committed to journaling every night before bed.

• A person who commits perjury can face criminal charges.
• The court ordered that he be committed to a treatment facility.

Case Study: How One Letter Can Change Professional Writing

The following is an illustrative scenario, not a report on a specific company.

Imagine a marketing manager named Priya preparing a proposal for a new client. The cover line reads: “We comit to delivering results in 90 days.” She is confident in her strategy, her pricing, and her portfolio.

The client skims the first page. A small typo in the headline sentence, the one about promises, quietly raises a question: If they miss details here, what else might they miss?

Priya’s work was strong, but the first impression suggested a lack of care. Readers often judge attention to detail from small signals like spelling, and a misspelling in a key sentence can undermine the message it carries. Irony makes it worse when the misspelled word is itself about reliability.

The lesson: 

In professional writing, small errors in important words cost more than they seem to. Proofread the sentences that carry your biggest claims first.

Common Mistakes People Make With Commit

Writing Comit Instead of Commit

The most frequent error.

• ❌ I want to comit to this goal.
• ✅ I want to commit to this goal.

Misspelling Committed

People often write one M, one T, or both wrong.

• ❌ comitted, commited, comittted
• ✅ committed (two M’s, two T’s)

Misspelling Commitment

Here the T is not doubled, because -ment starts with a consonant.

• ❌ comitment, committment
• ✅ commitment (two M’s, one T)

Using the Wrong Phrase

• ❌ commit in a relationship → ✅ commit to a relationship
• ❌ commit a favor → ✅ do a favor
• ❌ commit a decision → ✅ make a decision (or “commit to a decision”)

Commit vs Submit

Both come from mittere, but they mean different things.

Word	Meaning	Example
Commit	Pledge, perform, or store	She committed to the plan.
Submit	Hand in or yield	Please submit your form by Friday.

Submit has only one M, because the prefix sub- ends in “b,” not “m.”

Commit vs Permit

Word	Meaning	Example
Commit	Pledge or carry out	He committed to the deal.
Permit	Allow	The rules do not permit pets.

Permit also doubles its T in permitted and permitting, just like commit.

Commit vs Omit

Word	Meaning	Example
Commit	Do or pledge	They committed to quality.
Omit	Leave out	Do not omit the date.

Omit has only one M, since o- is the prefix. It still doubles the T: omitted, omitting.

Memory Tricks to Remember the Correct Spelling

The Double Effort Rule

To commit, you need double effort. So the word gets double M’s. Silly, but it sticks.

The Commitment Trick

Picture two people shaking hands: M and M. A commitment is a mutual promise, so it takes two M’s to hold it together.

Visual Memory Trick

Look at the word’s shape: com-MIT. The two M’s look like two small hills standing side by side, with the “i” and “t” following like a flag and a signpost. Write it by hand three times and the image tends to stay.

Why Correct Spelling Matters

Spelling is a quiet signal of credibility. Here is why it matters:

First impressions:

 Typos can make readers doubt your attention to detail.

Search visibility: 

Misspelled keywords may not match what people search for.

Clarity: 

Odd spellings slow readers down and break their flow.

Professionalism:

 Résumés, cover letters, and contracts are judged closely.

Trust: 

Clean writing makes your message feel reliable.

For a word that literally means “to pledge,” getting it right is a small but worthwhile habit.

Synonyms and Antonyms of Commit

Meaning	Synonyms	Antonyms
Pledge	promise, vow, dedicate, devote, pledge	renege, withdraw, back out
Perform	carry out, perpetrate, execute, do	prevent, avoid, refrain
Entrust	assign, hand over, consign	withhold, retain
Allocate	allot, set aside, earmark	withdraw, release

Tip: Use “perpetrate” instead of “commit” when you want a more formal tone for crimes. Use “pledge” or “dedicate” when “commit” feels overused.

Easy Tricks to Remember the Correct Spelling

Here is a quick checklist you can save:

Say it in parts:

 com + mit.

Link it to family words: 

committee, commitment, committed.

Check the stress:

 last-syllable stress means double the T when adding endings.

Think of the prefix:

 com- + mit keeps both M’s.

Proofread important words twice: 

especially ones tied to promises.

Add it to your dictionary: 

train your phone and keyboard to flag the error.

Final Thought

The answer to “commit vs comit” is simple: commit is right, comit is not. Two M’s come from the prefix com- meeting the root mit, and the same double M carries through committed, commitment, and committee.

Remember the rules, and spelling this word becomes automatic:

• Always use two M’s.
• Double the T for committed and committing.
• Keep a single T in commitment.
• Use “commit to,” not “commit in.”

Next time you write a promise, make sure the word itself is spelled with the same care. That small detail helps your writing look polished and trustworthy.
