Tomorrow vs Tommorow: Which Spelling Is Correct?

The only correct spelling is tomorrow.

Many people mistakenly write tommorow because the pronunciation makes it sound as though there are two m letters. However, English spelling follows historical word formation rather than pronunciation alone.

Correct:

• I’ll finish the report tomorrow.
• We have an exam tomorrow morning.
• See you tomorrow.

Incorrect:

• I’ll finish the report tommorow.
• We leave tommorow.
• The meeting is tommorow.

Using the correct spelling makes your writing appear more professional and trustworthy.

Quick Answer

If you’re wondering whether tomorrow or tommorow is correct, here’s the simple answer:

✅ Tomorrow is the correct spelling.
❌ Tommorow is a misspelling and should never be used in formal or informal writing.

Whether you’re writing an email, text message, essay, or social media post, always choose tomorrow.

Why Is “Tommorow” Wrong?

The misspelling tommorow usually happens because English pronunciation can be misleading.

When we say the word aloud, it may sound like there are two m letters. However, English spelling doesn’t always match pronunciation exactly.

The correct letter pattern is:

• To
• Morrow

Together, they form:

Tomorrow

Many dictionaries list tommorow as a common misspelling, but not as a valid English word.

Quick Memory Trick

One of the easiest ways to remember the spelling is:

Tomorrow has ONE M and TWO Rs.

Think of it like this:

• ✅ One M
• ✅ Two Rs

Another easy trick:

Today → Tomorrow

Both words start with To.

Or remember this phrase:

Borrow tomorrow’s R, not another M.

These small memory tricks can help you avoid making the same mistake repeatedly.

What Does “Tomorrow” Mean?

Notice that pronunciation doesn’t include an extra m, even though many learners mistakenly hear one.

Common Mistakes People Make

Although tomorrow is a simple everyday word, many people accidentally misspell it. Here are the most common errors:

Incorrect Spelling	Correct Spelling
Tommorow	✅ Tomorrow
Tommorrow	✅ Tomorrow
Tomorow	✅ Tomorrow
Tomarrow	✅ Tomorrow

All of these are considered spelling mistakes. Major dictionaries recognize tomorrow as the only correct spelling.

Why Do People Misspell “Tomorrow”?

There are several reasons why this mistake happens.

1. Pronunciation Can Be Misleading

When spoken quickly, some people think they hear two m letters instead of one.

For example:

• Correct pronunciation: tuh-MOR-oh
• Incorrect assumption: tom-mor-row

Because English spelling doesn’t always match pronunciation exactly, writers sometimes insert an extra m.

2. Typing Too Quickly

Fast typing often leads to accidental double letters.

Examples:

• tommorow
• tommorrow

This is especially common on smartphones and social media.

3. Confusing Letter Patterns

Many English words legitimately contain double m letters, such as:

• common
• summer
• committee

Because of this, learners sometimes assume tomorrow follows the same pattern but it doesn’t.

4. Lack of Proofreading

Even experienced writers occasionally type tommorow without noticing.

A quick proofreading pass or spell checker usually catches the error before publishing.

Easy Ways to Remember the Correct Spelling

If you often forget the spelling, these tricks can help.

Trick 1: One M, Two Rs

Remember:

Tomorrow = 1 M + 2 Rs

This is the easiest rule for most learners.

Trick 2: Break the Word

Split it into smaller parts:

To + Morrow

The second part, morrow, is an old English word related to the next day or morning, which explains why the modern spelling contains only one m.

Trick 3: Visual Practice

Write the word several times:

• Tomorrow
• Tomorrow
• Tomorrow
• Tomorrow

Repeated writing helps build muscle memory.

Trick 4: Use It in Sentences

The more often you use the correct spelling, the easier it becomes to remember.

Examples:

• I’ll visit my grandparents tomorrow.
• We have a football match tomorrow.
• Tomorrow is another opportunity to improve.

Tomorrow in Everyday Writing

The word appears in many types of writing.

Emails

I’ll send the updated document tomorrow.

School Assignments

The project is due tomorrow morning.

Workplace Communication

Let’s continue this discussion tomorrow.

Casual Conversations

Are you free tomorrow evening?

Using the correct spelling creates a better impression and avoids unnecessary corrections.

American vs British English

Unlike words such as color/colour or organize/organise, there is no spelling difference between American English and British English.

Both use:

✅ Tomorrow

Neither variety accepts tommorow as correct.

Quick Checklist

Before publishing anything, ask yourself:

• ✅ Did I write tomorrow?
• ✅ Did I avoid writing tommorow?
• ✅ Did I proofread my writing?
• ✅ Did my spell checker confirm the spelling?
• ✅ Does every sentence look natural?

If you answered “Yes” to all five, you’re using the correct spelling confidently.

Real-Life Example: How One Small Spelling Mistake Changed a First Impression

Imagine Sarah, a university student applying for a summer internship. She carefully prepared her resume and wrote a professional email to the hiring manager.

At the end of her message, she wrote:

“I look forward to hearing from you tommorow.”

Everything else in the email was excellent, but the spelling mistake stood out immediately. While the employer didn’t reject her because of one typo, it created the impression that the email hadn’t been proofread.

Before sending a follow-up message, Sarah reviewed her writing with a spell checker and noticed the mistake. She corrected tommorow to tomorrow and made proofreading a habit before sending important documents.

This simple experience taught her an important lesson: small spelling mistakes can affect how professional your writing appears. Whether you’re applying for a job, submitting schoolwork, writing business emails, or publishing blog content, correct spelling helps build credibility and confidence.

Fortunately, mistakes like tommorow are easy to avoid once you remember the rule:

Tomorrow = One M + Two Rs

A few extra seconds of proofreading can save you from embarrassing spelling errors and leave a stronger first impression.
