When you mean the day after today, the correct spelling is tomorrow. The version tommorow looks close, but it is not a standard spelling. In normal English, tomorrow keeps one m and two r’s.
Correct Choice at a glance
The correct form is always tomorrow; tommorow is a misspelling.
Correct Spelling and Core Meaning
Tomorrow means the day after today, and it can also mean the future in a general sense. In edited English, tomorrow is the accepted spelling, and common misspellings include tommorow. ✅Source
Letter Order that matters
The fixed pattern is t-o-m-o-r-r-o-w: one m, two r’s, and it ends with -ow.
- ✅ Correct tomorrow (standard spelling)
- ❌ Wrong tommorow (extra m, missing r)
Where the Spelling Comes From
A big clue is the older word morrow, which means the next day (and, in older usage, morning). That’s why tomorrow carries the double r you see in morrow. ✅Source
- Morrow
- The next day (and historically morning).
- Tomorrow
- The day after today and, sometimes, the future.
Why the Misspelling Happens
Tommorow usually shows up because the sound of the word doesn’t “announce” the spelling clearly. People often double the m by instinct, then they drop one r without noticing. The correct form tomorrow keeps a single m and a double r.
- Consonant swap: doubling m instead of doubling r.
- Fast typing: extra letters slip in, especially around mm and rr.
- Autocorrect gaps: a device may not catch tommorow in every app, even though tomorrow is standard.
Spelling logic is simple once you see it: tomorrow visually contains morrow, so the double r is the part that “belongs.”
Pronunciation and Letter Pattern
In dictionaries, tomorrow is shown with stress on the middle: tə-MOR-row (phonetic spellings vary by dictionary). That middle stress is one reason the mm mistake feels “natural” to the eye, even though the correct spelling is rr.
What You Actually See
The key visual is the core chunk -morrow. The correct full word is to + morrow, not tom + morow.
Grammar and Punctuation Notes
Tomorrow works as an adverb (“We leave tomorrow”) and as a noun (“See you tomorrow”). In both roles, the spelling stays exactly the same, and tommorow remains incorrect.
As an Adverb
It answers when: “Call me tomorrow.” No article is needed, and tommorow is not used in standard writing.
As a Noun
It can act like a “thing”: “Tomorrow is busy.” You’ll also see tomorrow paired with nouns like morning or afternoon.
For possession, tomorrow’s with an apostrophe is standard for a singular noun (“tomorrow’s schedule”). The apostrophe shows possession, not a plural, and the base spelling stays tomorrow. ✅Source
| Form | Role | Example Use | Status |
|---|---|---|---|
| tomorrow | Adverb / Noun | “We meet tomorrow.” / “Tomorrow is full.” | ✅ Correct |
| tomorrow’s | Possessive (singular) | “Tomorrow’s agenda is short.” | ✅ Correct |
| tommorow | Misspelling | Often typed by accident | ❌ Wrong |
| tomorow | Misspelling | Missing one r | ❌ Wrong |
Common Variants and Lookalikes
Tomorrow gets misspelled in a few predictable ways. The big pattern is “wrong double letter”: mm shows up where rr should be. In standard English, only tomorrow is correct, and tommorow stays nonstandard.
Typical mix-ups include tommorow, tommorrow, and tomarrow. They look “close,” but they don’t match the accepted spelling tomorrow.
- ❌ Wrong tommorow (extra m)
- ❌ Wrong tommorrow (extra m, still off)
- ❌ Wrong tomorow (missing an r)
- ❌ Wrong tomarrow (vowel shift that doesn’t belong)
Examples in Context
These examples keep tomorrow in its standard form, whether it works as an adverb or a noun. Notice how the spelling never changes, and tommorow never appears in careful writing.
- “I’ll reply tomorrow.”
- “We’re traveling tomorrow morning.”
- “Tomorrow looks busy, but manageable.”
- “Let’s confirm tomorrow’s time slot.”
Same Word two time meanings
Literal: the day after today. Figurative: a general future time. In both uses, the spelling stays tomorrow, not tommorow.
