Why Is “Tommorow” Wrong?
The word comes from Old English “to morgen,” meaning “in the morning.” Over time it became “to-morrow” and then “tomorrow.” The first part “to” has one M sound. The second part “morrow” brings the second M. So there is no room for a third M. This is the heart of Tomorrow vs Tommorow.
Steps to see the error:
- Split the word: to + morrow.
- Put them back together: tomorrow.
- Notice that “tommorow” adds a letter that has no source.
Example: “I will call you tommorow.” The extra M and missing R make it wrong.
Correct
- tomorrow
- “See you tomorrow.”
Incorrect
- tommorow
- “See you tommorow.”

- Check the middle letters: “-mor-” vs “-mmor-.”
- Check the ending: “-row” with two R’s is right.
Example: “Tomorrow is Friday.” (correct) vs. “Tommorow is Friday.” (wrong)

Why Do People Spell Tomorrow as “Tommorow”?
Most people know the meaning. They just mix up the letters. This is why Tomorrow vs Tommorow is a popular search.
Steps to avoid the trap:
- Slow down when you write this word.
- Say it in parts: to-mor-row.
- Check the spelling before you send.
Example: A student types “tommorow” in a text. A quick re-read fixes it.
1. The double letters are confusing
The word has one double letter (RR). Writers often move the double to the M. Example: tommorow.
2. The pronunciation does not clearly reveal the spelling
You say “tuh-MAR-oh.” The sound gives no clue about the double R. Example: “tuh-mar-oh” can be typed many ways.
3. Fast typing causes mistakes
Fingers hit M twice when typing fast. Example: “tommorow” in a quick chat.
4. The word has an unusual spelling pattern
Many English words double the middle consonant. This word doubles only the second one. Example: compare “tomorrow” with “tomato.”
How Do You Pronounce Tomorrow?
In American English, say “tuh-MAHR-oh.” The stress falls on the second syllable.
