Quick Answer
Tomorrow is the correct spelling, while tommorow is incorrect. The difference between tomorrow vs tommorow is only spelling: tomorrow means the day after today or a future time and uses one m with two r’s. Use tomorrow in everyday writing, emails, and formal communication to avoid this common spelling mistake.
Tomorrow Vs Tommorow At A Glance

| Form | Correct Or Incorrect | Meaning | Use It? |
|---|---|---|---|
| tomorrow | Correct | The day after today; the future | Yes |
| tommorow | Incorrect | Misspelling of tomorrow | No |
The difference is not meaning. The difference is spelling. Tomorrow is the standard word. Tommorow is a common spelling error.
Why Tomorrow Is Correct

Tomorrow means “the day after today.”
Examples:
- I have a meeting tomorrow.
- We leave for Chicago tomorrow morning.
- The store opens at 9 a.m. tomorrow.
Tomorrow can also refer to the future in a broader way.
Examples:
- Today’s students are tomorrow’s leaders.
- We need better plans for tomorrow.
- The technology of tomorrow may look very different.
In these sentences, tomorrow is the only correct spelling.
Why Tommorow Is Wrong

Tommorow is a misspelling of tomorrow. It is not a separate word, a regional spelling, or a formal variant.
Incorrect: The deadline is tommorow.
Correct: The deadline is tomorrow.
Incorrect: Tommorow is my first day at work.
Correct: Tomorrow is my first day at work.
Readers will usually understand tommorow, but it still looks like an error. That matters in school assignments, resumes, business emails, job applications, blog posts, and any public writing.
How To Remember The Correct Spelling

The easiest rule is:
Tomorrow = one m, two r’s
Break it into this pattern:
to + morrow = tomorrow
The older word morrow refers to the next day or morning. You do not need to use morrow in normal modern writing, but it can help you remember the spelling.
Think of it this way:
- to = t-o
- morrow = m-o-r-r-o-w
- tomorrow = t-o-m-o-r-r-o-w
That gives you one m and two r’s.
Why People Misspell Tomorrow
People often write tommorow because the word sounds like it might need a double m. The stress falls near the middle of the word, so the spelling can feel heavier than it is.
Fast typing also causes the mistake. Once your fingers double one letter, it is easy to double the wrong one.
Common wrong forms include:
| Misspelling | Problem | Correct Form |
| tommorow | Extra m | tomorrow |
| tommorrow | Extra m and extra confusion | tomorrow |
| tomorow | Missing one r | tomorrow |
| tomarrow | Wrong vowel sound | tomorrow |
| tomorro | Missing final w | tomorrow |
The safest fix is to check for the pattern: one m, two r’s, final w.
Tomorrow As An Adverb
Tomorrow often works as an adverb. That means it tells when an action happens.
Examples:
- I’ll email the file tomorrow.
- She starts training tomorrow.
- We can review the draft tomorrow.
- The package should arrive tomorrow afternoon.
In these examples, tomorrow answers the question when?
When will I email the file? Tomorrow.
When does she start training? Tomorrow.
Tomorrow As A Noun
- Tomorrow can also work as a noun. In this use, it names the next day or a future time.
Examples:
- Tomorrow is Friday.
- Tomorrow will be busy.
- We are planning for a better tomorrow.
- No one knows what tomorrow will bring.
When tomorrow starts a sentence, capitalize it like any other first word.
Correct: Tomorrow is the deadline.
Incorrect: tommorow is the deadline.
When To Use A Date Instead Of Tomorrow
Tomorrow is clear when the reader knows the current date. However, exact dates work better for deadlines, contracts, schedules, and official notices.
Less Clear: Please send the signed form tomorrow.
Clearer: Please send the signed form by July 6, 2026.
Less Clear: The office will reopen tomorrow.
Clearer: The office will reopen on July 6, 2026.
Use tomorrow for normal conversation. Use an exact date when the timing must be precise.
