Typing quickly and wondering if you just wrote “tommorow” by mistake? You are not alone. This is one of the most searched spelling questions in English, and the confusion makes sense once you see how the word is built.
Below is the quick answer, the reasoning behind it, and simple ways to lock the correct spelling into memory.
Quick Answer
Tomorrow is the only correct spelling. It has one m and two r’s.
Tommorow, along with variants like tommorrow and tomarrow, is always a misspelling and should never appear in formal or casual writing.

| Letter count | 8 letters | 8 letters |
| M count | One m | Two m’s (wrong) |
| R count | Two r’s | One r (wrong) |

Which is correct, tomorrows or tomorrow’s?
It depends on grammar function. Use tomorrow’s as a possessive, such as “tomorrow’s weather” or “tomorrow’s meeting.” Use tomorrows only as a rare plural noun, as in “we can’t predict all our tomorrows.” In everyday writing, tomorrow’s with an apostrophe is the form you will need most often.
Is tomorrow double R?
Yes. Tomorrow doubles the r, not the m. The correct breakdown is t o m o r r o w, with a single m followed by two r’s. This is the detail that trips up most writers, since the word sounds like it stresses both letters equally when spoken.
Why is tomorrow hard to spell?
Tomorrow is a classic phonetic mismatch. The middle syllable “morr” carries heavy stress, so the brain assumes both consonants around it should be doubled. This leads writers to double the m by habit, even though English spelling rules only call for the r to double here.
Is “to morrow” spelled correctly?
Not anymore. “To morrow” was the original two word form used in Old and Middle English, where morrow meant morning or the next day. The two words merged over time, and “to morrow” as two separate words is now outdated and incorrect.
How do Americans spell tomorrow?
American English and British English spell tomorrow identically. Unlike color versus colour, there is no regional variation here. One m and two r’s is the standard spelling everywhere English is used.
Why do we say “tomorrow” and not “morrow”?
We say tomorrow because the word combines to and morrow, meaning “on the next morning.” Morrow alone survived as a poetic or archaic word for the next day, but it faded from everyday speech while tomorrow became the standard term.
Is it ever correct to spell it “tommorrow”?
No. Tommorrow, with both a double m and a double r, is never correct in any context, dialect, or style guide. It combines two mistakes into one word and should always be corrected to tomorrow.
What is the old-fashioned way to say “tomorrow”?
The archaic or old-fashioned term is simply morrow, often seen in phrases like “on the morrow” in classic literature and poetry. It appears throughout Shakespearean and medieval English texts, where it functioned the way we use tomorrow today.
When did morrow become morning?
Morrow and morning share the same Old English root, morgen, meaning the early part of the day. Over time, English speakers began using morning for the start of the day and reserved morrow mainly for references to the next day.
When did “tomorrow” become a word?
Tomorrow developed during the Middle English period, when “to morwe” or “to morewen” gradually fused into a single written word. By the time Modern English took shape, tomorrow was firmly established, and the separated version had disappeared from standard use.
How do you remember to spell tomorrow?
A popular memory trick breaks the word into its two building blocks:
- Start with to, which has one letter t and one letter o.
- Add morrow, which has one m, two r’s, and one w.
- Combine them and you get one m total and two r’s total, which is exactly the pattern in tomorrow.
Some writers also use the phrase “one m today, two r’s tomorrow” as a quick mental cue while typing.
How can you remember spellings easily?
Beyond tomorrow, general spelling retention improves with a few consistent habits:
- Read regularly so correct spellings become visually familiar.
- Say tricky words out loud in syllables instead of relying on how they sound in fast speech.
- Keep a running list of words you personally misspell often.
- Use spellcheck as a backup, not a replacement for proofreading.
Tomorrow Vs Tommorow At A Glance
Tomorrow is the accepted standard spelling used in dictionaries, newspapers, and formal documents worldwide. Tommorow is a widespread typo that shows up in texts, emails, and social posts, usually from typing speed rather than real confusion about meaning.
Why Tomorrow Is Correct
Tomorrow follows its historical word origin exactly. It comes from to plus morrow, and that structure naturally produces one m and two r’s. Every major dictionary lists tomorrow as the sole accepted spelling.
Why Tommorow Is Wrong
Tommorow breaks the word’s natural structure by adding a second m that does not belong to either the “to” or the “morrow” part. It is a phonetic spelling error, not an alternate form or regional variant. No style guide accepts it.
How To Remember The Correct Spelling
Try these quick memory tips the next time you are unsure:
- Break the word into to plus morrow before you type it.
- Picture the double r sitting in the middle, since that is the only doubled letter.
- Say the word slowly and tap once for the m and twice for the r.
- Compare it to similar words like borrow and sorrow, which also double the r and not the first consonant.
Why People Misspell Tomorrow
Most misspellings come down to typing speed and pronunciation habits. Writers hear the stressed “morr” sound and assume the letter before it should double too. Autocorrect catches this on many devices, but on platforms without spellcheck, tommorow slips through unnoticed.
Tomorrow As An Adverb
As an adverb, tomorrow describes when an action will happen. For example, “She will call tomorrow” or “We are traveling tomorrow morning.” In this role, tomorrow modifies the verb and answers the question of when something will take place.
Tomorrow As A Noun
As a noun, tomorrow refers to the day itself or, more broadly, the future. For example, “Tomorrow is a holiday” uses it as a subject, while “Today’s choices shape tomorrow” uses it to represent the future in general terms.
How To Use Tomorrow Correctly In A Sentence
Keep these usage guidelines in mind:
- Use tomorrow without an apostrophe when referring to the day itself, as in “See you tomorrow.”
- Use tomorrow’s when showing possession, as in “tomorrow’s forecast looks clear.”
- Avoid combining tomorrow with a specific date, since the two convey the same information in different ways.
When To Use A Date Instead Of Tomorrow
In scheduling emails, contracts, or any message that might be read after the current day has passed, a specific calendar date is clearer than tomorrow. A message read a week later loses meaning if it only says “the meeting is tomorrow,” so writing “the meeting is on August 11” avoids confusion entirely.
Correct Examples In Everyday Writing
- I promised my landlord I would drop off the rent tomorrow morning before work.
- The flight to Chicago leaves tomorrow at six, so we need to pack tonight.
- Tomorrow’s team meeting has been moved to the third floor conference room.
- Today’s habits quietly decide what tomorrow will look like.
Incorrect Vs Correct Sentence Fixes

| Can we meet tommorow instead? | Can we meet tomorrow instead? |
| The store opens tommorow at nine. | The store opens tomorrow at nine. |
Common Phrases With Tomorrow

- Here today, gone tomorrow

- A better tomorrow
- Tomorrow’s leaders
Synonyms And Alternatives For Tomorrow
Depending on context, you can swap tomorrow for the next day, the following day, or, in more formal or literary writing, the morrow. For broader references to the future, phrases like the days ahead or what lies ahead work well as natural alternatives.
Final Thoughts
Tomorrow will likely stay on the list of commonly misspelled English words simply because of how it sounds when spoken. The fix is straightforward once you know the pattern: one m from “to,” two r’s from “morrow.”
Whether you are writing a quick text or a formal report, remembering that single detail is enough to spell tomorrow correctly every time, without needing to second guess yourself again.
