You are typing a quick text. You write “see you tommorow.” Something looks off. Is it two M’s or two R’s? Many people stop at this exact spot. The word has a double letter, but it is easy to put it in the wrong place.
Here is the answer. Tomorrow is the correct spelling. Tommorow is a misspelling. This guide on tomorrow vs tommorow explains the spelling, the meaning, and a trick to remember it. Do not worry if you have made this mistake. Plenty of writers have.
Tomorrow vs Tommorow: The Quick Answer
Tomorrow is the correct spelling. Tommorow is a common misspelling.
The right word has one M and two R’s. Spell it like this: t-o-m-o-r-r-o-w. That is eight letters.
Tommorow is not a second option. It is not a British or American style. It is just a slip.
Both versions sound the same when you say them. That is why the mistake is so common. Your ear cannot help you here. You have to know how the word looks on the page.
What Does Tomorrow Mean?
Tomorrow means the day after today. If today is Monday, tomorrow is Tuesday. It points to the next day on the calendar.
The word can also mean the future in a wider sense. You may hear “the leaders of tomorrow.” Here, the word is not about one single day. It means the time that lies ahead.
Dictionaries list both meanings under one spelling. So the meaning never changes the letters. Whether you mean the next day or the far future, you write tomorrow.
Why Do People Spell It Tommorow?
Spelling mistakes usually have a reason. This one has a few.
First, the word has a double letter, and people remember that. But they place it in the wrong spot. The double letter is R, not M.
Second, the first part of the word looks like the name Tom. It is easy to think of “Tommy” and add a second M.
Third, fast typing makes it worse. Fingers repeat letters without asking your brain. That mix explains most of the tomorrow vs tommorow mix-ups you see online.
Even strong writers pause on this word. It is a normal part of learning English.
How Do You Spell Tomorrow Correctly?
Break the word into three beats: to-mor-row. Write each beat one at a time.
Now try this trick. Split the word into two small words: “to” and “morrow.” Morrow has one M and two R’s. Add “to” in front, and you are done.
Here is another way to picture it. The two R’s stand side by side like the two rails of a train track. One M sits alone before them. A simple trick like this makes tomorrow vs tommorow easy to settle for good.
Read the word out loud while you type it. Say “to,” then “mor,” then “row.” Your fingers will follow the beats.
Where Does the Word Tomorrow Come From?
The word is old. In Old English, people used a phrase like to morgenne. It meant “in the morning” or “on the next morning.” The word morgen meant morning.
Over time, morgen changed into morrow. The word “morrow” still exists today. You may see it in old or poetic writing, such as “the morrow.”
Later, writers joined the two parts. For a long time, many wrote it with a hyphen: to-morrow. The hyphen faded in the twentieth century, and today we write one word.
Notice something in this history. There is no double M anywhere. The spelling tommorow has no support from the word’s past.

How Do You Pronounce Tomorrow?
In American English, the word has three syllables. Most people say tuh-MAWR-oh or tuh-MAHR-oh. The stress falls on the middle syllable.
The first sound is soft. It is a quick “tuh.” The last sound is a clear “oh.”
In fast speech, the ending can sound like “uh.” You may hear “tuh-MAHR-uh.” That is normal.
Now you can see the problem. The spoken word gives no clue about the double R. It also gives no clue that there is only one M. So the spelling has to be learned by sight.
Is Tomorrow a Noun, an Adverb, or Both?
It can be both. That makes it flexible.
As a noun, it names a day: “Tomorrow is my birthday.” As an adverb, it tells when something happens: “I will call you tomorrow.”
Tomorrow can also add a time to another noun, as in “tomorrow morning” or “tomorrow night.” It has a possessive form too: “Tomorrow’s meeting starts at nine.”
The plural, tomorrows, is rare. You may see it in poetic lines like “all our tomorrows.” Tomorrow is not a verb.
American and British English spell the word the same way. There is no regional difference to learn.
