Tomorrow is the correct spelling. Tommorow is a common misspelling. The correct form has one m and two r’s: t-o-m-o-r-r-o-w.
Because the word is common and its pronunciation does not clearly show every letter, it is easy to type the wrong version. This guide explains the correct spelling, meaning, word forms, common mistakes, examples, and practical ways to remember it.
Tomorrow vs Tommorow at a Glance
| Spelling | Status | Meaning |
|---|---|---|
| tomorrow | Correct | The day after today |
| tommorow | Incorrect | Common misspelling of tomorrow |
The main spelling trap is the middle of the word. Writers sometimes add a second m because the word looks as if it should contain one, while others remember the double r incorrectly.
What Does Tomorrow Mean?
Tomorrow is a noun and adverb related to time. It normally means the day after today.
- I will call you tomorrow.
- The meeting is tomorrow morning.
- We can finish the project tomorrow.
- Tomorrow will be a busy day.
The word is used constantly in everyday English, so spelling it correctly is useful in texts, emails, schoolwork, schedules, and professional communication.
Why Is Tomorrow the Correct Spelling?
The standard spelling is tomorrow, with one m and two r’s. Write the letters as:
t-o-m-o-r-r-o-w
The incorrect form tommorow adds an extra m. It may feel natural because the word is pronounced quickly, but pronunciation is not a reliable way to reconstruct every letter in English spelling.
A simple visual check is to focus on the middle: mo rr. The word has one m, followed later by two r’s.
Tomorrow vs Tommorow: Which One Is Correct?
If you are deciding between the two spellings, there is no regional English difference to consider. Use tomorrow in American English and British English.
| Form | Correct? |
|---|---|
| tomorrow | Yes |
| tommorow | No |
So you should not treat tommorow as an informal alternative. It is simply a spelling error.
Why Do People Misspell Tomorrow?
There are several reasons this mistake happens. The first is memory. The word has a repeated sound pattern, and writers may insert an extra consonant while typing.
Fast typing can also cause the error. Because tomorrow is familiar, people often type it without consciously checking each letter. Autocorrect may catch some mistakes, but it is better to know the correct form yourself.
- Confusing the middle letters
- Typing quickly
- Remembering the sound instead of the spelling
- Seeing the misspelling repeatedly online
Common Tomorrow Spelling Mistakes
- ❌ tommorow
- ✅ tomorrow
- ❌ tomorow
- ✅ tomorrow
- ❌ tommorrow
- ✅ tomorrow
These errors are different versions of the same problem: the writer has changed the standard letter pattern. When proofreading, check that there is exactly one m and two r’s.
How to Remember the Spelling of Tomorrow
Use the phrase one m, two r’s. That gives you a quick checklist:
to + m + o + rr + ow
You can also write the word a few times while saying the letters in your head. The goal is to make the visual pattern familiar rather than relying only on pronunciation.
Another useful technique is to compare the correct and incorrect forms directly: tomorrow versus tommorow. The extra m in the second version should stand out once you know what to look for.

Knowing the grammar role is useful, but the spelling does not change between these uses.
