Some words seem so familiar that you never expect to spell them incorrectly.
Tomorrow is one of those words. You use it in emails, text messages, school assignments, and everyday conversations. Yet, when it's time to type it, many people accidentally add an extra
"m" and end up with
"tommorrow."If you've ever paused and wondered which spelling is correct, you're not alone. This is one of the most common spelling mistakes in English. The good news is that once you understand why it happens, remembering the correct version becomes much easier.The Correct SpellingLet's settle the question right away.The correct spelling is
tomorrow.It has:
Spellings such as
tommorrow,
tomorow,
tommorow, and
tomarrow are all incorrect. They don't appear as accepted
spellings
in English dictionaries, regardless of whether you're using American or British English.Since "tomorrow" is a word we use almost every day, getting it right helps your writing look polished and professional.How "Tomorrow" Is UsedThe word
tomorrow can serve two different grammatical purposes.As a
noun, it refers to the day after today.
Example:
- Tomorrow will be much busier than today.
As an
adverb, it tells us when something will happen.
Example:
- I'll finish the report tomorrow.
No matter how it's used, the spelling always stays exactly the same.Why People Write "Tommorrow"The mistake usually comes from the way we pronounce the word.When we say
tomorrow, the middle sound feels strong, making it seem like there should be two
ms. Our brains naturally look for familiar spelling patterns, and English contains many words with doubled letters in the middle, such as:
- accommodate
- committee
- occurred
Because of these examples, it's easy to assume that
tomorrow follows the same pattern. It doesn't.Instead, the word contains only one
m, even though many people instinctively type two.Fast typing can make the problem even worse. Your fingers may repeat the
m without you noticing until after you've finished the word.The History Behind the WordThe spelling makes much more sense when you understand where the word came from.
Tomorrow developed from two older English words:
The first part contributes the single
m, while
morrow provides the double
r. Over hundreds of years, these two words merged into one, giving us the modern spelling we use today.The word
morrow once meant "the next day" or "the following morning." Although it's rarely used in modern English, it still appears in older expressions like
good morrow.Knowing this history makes the spelling easier to remember because you can clearly see where each letter belongs.Easy Ways to Remember the Correct SpellingYou don't have to memorize the entire word as one long string of letters. Instead, try one of these simple techniques.
Break it into two parts.Think of it as:
to + morrowThis reminds you that the word starts with only one
m.
Remember similar words.Words like
borrow and
sorrow share the same
-orrow ending with two
rs. Once you notice the pattern, it becomes easier to spell
tomorrow correctly.
Practice using it.Writing the word in complete sentences helps build muscle memory much faster than simply repeating the spelling.For example:
- I'll call you tomorrow.
- We are leaving tomorrow morning.
- Tomorrow is another opportunity to improve.
The more often you write it correctly, the more natural it becomes.Why Correct Spelling MattersA single extra letter may not seem important, but common spelling mistakes can leave a lasting impression.In professional emails, job applications, academic papers, and business communication, frequently misspelled everyday words can make your writing appear rushed or careless. Readers often notice errors in familiar words more quickly than mistakes in uncommon vocabulary.While everyone makes typing mistakes from time to time, consistently spelling common words correctly helps your writing appear more confident and reliable.Don't Depend Entirely on Spell CheckModern writing tools like Microsoft Word, Google Docs, and Grammarly usually detect
tommorrow immediately.However, spell check isn't available everywhere. Messaging apps, online forms, note-taking apps, and some mobile keyboards may not always catch the mistake. Even autocorrect can occasionally create unexpected errors.That's why it's worth taking a quick look at words you know you often misspell instead of relying entirely on software.Final ThoughtsThe answer is simple:
tomorrow is the only correct spelling, while
tommorrow is always incorrect.Once you remember that the word comes from
to + morrow, the spelling becomes much easier to understand. Pair that knowledge with regular practice, and you'll soon find yourself typing
tomorrow correctly without stopping to think about it.
