Tomorrow refers to the day that comes after today. It is commonly used when talking about future time, plans, events, schedules, appointments, dates, deadlines, and upcoming activities. If you’ve come across the word “tomorrow” and wondered what it means, how it is used, or how it works in different sentences, the term is closely connected to today, yesterday, the future, the next day, upcoming events, and time expressions.
The tomorrow meaning refers to the day following the present day. The exact date represented by “tomorrow” changes depending on when the word is used. For example, if today is Monday, tomorrow is Tuesday. Words and expressions such as the next day, the following day, the day after today, soon, and in the future are related to tomorrow but can have slightly different meanings and uses.
In this guide, you’ll learn what “tomorrow” means, how to use it in sentences, whether it is a noun or adverb, and how “tomorrow” differs from related expressions such as “the next day,” “today,” and “yesterday.” You’ll also see clear examples to make the meaning easy to understand.
By the end, you’ll know exactly what tomorrow means and how to use this common time-related word naturally and correctly.
What Does Tomorrow Mean?
The basic tomorrow meaning is the day after today.
If today is Monday, tomorrow is Tuesday. If today is Friday, tomorrow is Saturday. The exact calendar date represented by tomorrow therefore changes every day.
Oxford defines tomorrow as the day after today and also gives a broader meaning related to the future.
Tomorrow meaning in simple English
You can remember the definition this way:
Tomorrow = the day after today.
For example:
- Today is Monday. Tomorrow is Tuesday.
- Today is June 10. Tomorrow is June 11.
- I have an appointment tomorrow.
- We are leaving tomorrow morning.
The word can also refer to an unspecified future:
Tomorrow’s workers will need new skills.
Here, tomorrow does not literally mean the next calendar day. It represents the future. Cambridge and Oxford both recognize this broader use.
Tomorrow Definition in English
The word tomorrow has two closely related meanings.
| Meaning | Explanation | Example |
| The day after today | The next calendar day | I will see you tomorrow. |
| The future | A time that has not yet arrived | We are building a better tomorrow. |
The first meaning is the one people use most often in ordinary scheduling and conversation.
The second meaning is more abstract. It appears frequently in discussions about plans, hopes, opportunities, technology, education, society, and the future.
For example:
The decisions we make today can affect tomorrow.
In this sentence, tomorrow can mean more than one specific date. It represents future circumstances.
Tomorrow or Tommorow: Which Spelling Is Correct?
Tomorrow is the correct spelling.
Tommorow is incorrect.
This is one of the most common spelling questions surrounding the word, which is why searches such as “tomorrow or tommorow,” “tomorrow spelling,” and “tomorrow or tommorow in English” are closely related.
| Spelling | Correct? | Why? |
| tomorrow | ✅ | Standard English spelling |
| tommorow | ❌ | Incorrect placement of the repeated consonant |
| tomorow | ❌ | Missing an r |
| tommorrow | ❌ | Contains an extra m |
| tomorrow | ✅ | Correct standard form |
The correct spelling is:
T-O-M-O-R-R-O-W
Notice the important pattern:
One M + two Rs
That simple pattern can help you avoid the most common spelling error.
Example
❌ I will finish the assignment tommorow.
✅ I will finish the assignment tomorrow.
❌ We are leaving tommorow morning.
✅ We are leaving tomorrow morning.
How to Spell Tomorrow Correctly
If you often hesitate over the spelling, break it into letters:
T – O – M – O – R – R – O – W
The most important thing to remember is that tomorrow has only one M.
It also has two Rs.
A useful spelling trick is:
Tomorrow has one M and two Rs.
Think of the word as:
TO + MORROW
The historical spelling helps explain why the modern word contains the sequence morrow. Oxford traces tomorrow to Middle English, originally formed from the preposition to and the word morrow.
Why Do People Spell Tomorrow as Tommorow?
The misspelling tommorow is easy to produce because English spelling does not always correspond perfectly to pronunciation.
A writer may remember that the word contains a repeated consonant but place the repetition on the wrong letter:
tommorow ❌
instead of:
tomorrow ✅
The correct written pattern is:
tom + orrow = tomorrow
The important distinction is:
- m appears once
- r appears twice
This is a spelling issue rather than a difference in meaning. Tommorow does not represent a separate English word with a different definition.
Tomorrow Pronunciation
The pronunciation of tomorrow varies slightly between English accents.
Oxford gives pronunciations including /təˈmɒrəʊ/ in British English and /təˈmɑːrəʊ/ in its learner dictionary entries. Its American dictionary gives American pronunciations such as /təˈmɑroʊ/ and /təˈmɔroʊ/.
Cambridge likewise lists different UK and US pronunciations.
For English learners, the most useful point is that the spelling is always:
tomorrow
even though pronunciation can vary by accent.
British and American pronunciation
| Variety | Approximate pronunciation |
| British English | tuh-MOR-oh |
| American English | tuh-MAHR-oh / tuh-MOR-oh |
The exact pronunciation can vary between speakers, so learners should use a dictionary audio recording when practicing.
Is Tomorrow a Noun or an Adverb?
One of the most useful grammar facts about tomorrow is that it can function as both a noun and an adverb.
Oxford lists separate noun and adverb entries for the word.
Tomorrow as an adverb
When tomorrow tells you when an action happens, it functions as an adverb.
Examples:
- I will call you tomorrow.
- She is leaving tomorrow.
- We are meeting tomorrow.
- They arrive tomorrow morning.
- He starts his new job tomorrow.
In:
I will call you tomorrow.
Tomorrow tells us when the action of calling will happen.
Oxford specifically describes this adverbial use as referring to something happening on or during the day after today.
Tomorrow as a noun
Tomorrow can also function as a noun.
Examples:
- Tomorrow is another day.
- We can deal with it tomorrow.
- Let’s leave the discussion until tomorrow.
- Tomorrow may bring new opportunities.
As a noun, tomorrow can refer to the actual next day or, in a broader sense, to the future. Oxford labels the noun as uncountable and gives both meanings.
A simple way to identify the difference
Ask what the word is doing in the sentence.
I will leave tomorrow.
Here, tomorrow tells you when you will leave, so it is functioning as an adverb.
Tomorrow will be busy.
Here, tomorrow is the subject of the sentence and refers to a day, so it functions as a noun.
Tomorrow in Sentences
Learning tomorrow meaning becomes easier when you see the word in different contexts.
Everyday examples
- I will see you tomorrow.
- Are you free tomorrow?
- She is coming tomorrow.
- We are going shopping tomorrow.
- Call me tomorrow.
- The weather should improve tomorrow.
- I have a doctor’s appointment tomorrow.
- They will arrive tomorrow afternoon.
School examples
- My exam is tomorrow.
- The assignment is due tomorrow.
- We have a class test tomorrow morning.
- I need to finish my essay by tomorrow.
- The teacher will explain the topic tomorrow.
Workplace examples
- The meeting is scheduled for tomorrow.
- I will send the report tomorrow morning.
- The manager will review the proposal tomorrow.
- Our deadline is tomorrow.
- We can discuss the budget tomorrow.
Future-oriented examples
- Nobody knows what tomorrow will bring.
- We should prepare for tomorrow.
- Today’s decisions can shape tomorrow.
- Young people are the leaders of tomorrow.
- The company is investing in the technology of tomorrow.
These examples show why tomorrow can move from a literal calendar reference to a broader idea of the future.
Tomorrow Morning, Tomorrow Afternoon, and Tomorrow Night
Tomorrow commonly combines with parts of the day.
Common expressions include:
- tomorrow morning
- tomorrow afternoon
- tomorrow evening
- tomorrow night
- tomorrow at noon
- tomorrow at 9 a.m.
Examples:
I will call you tomorrow morning.
The flight leaves tomorrow afternoon.
We are having dinner tomorrow night.
The office opens tomorrow at 9 a.m.
Oxford specifically lists combinations such as tomorrow morning, tomorrow afternoon, tomorrow evening, and tomorrow night.
Is tomorrow morning correct?
Yes.
Tomorrow morning means the morning of the day after today.
For example, if today is Monday:
tomorrow morning = Tuesday morning
Is tomorrow night correct?
Yes.
I’ll finish it tomorrow night.
This means the night following today.
The same pattern applies to other periods:
tomorrow + time period
For example:
- tomorrow morning
- tomorrow afternoon
- tomorrow evening
- tomorrow night
Is Tomorrow’s Correct?
Yes. Tomorrow’s is the possessive form of tomorrow.
It commonly appears before a noun.
Examples:
- tomorrow’s meeting
- tomorrow’s weather
- tomorrow’s schedule
- tomorrow’s newspaper
- tomorrow’s game
Compare these sentences:
I’ll attend the meeting tomorrow.
I’ll attend tomorrow’s meeting.
In the first sentence, tomorrow identifies when the action happens.
In the second, tomorrow’s identifies which meeting is being discussed.
Cambridge provides examples such as tomorrow’s meeting and tomorrow’s game, confirming this standard usage.
Tomorrow or the Day After Tomorrow?
These expressions refer to different days.
| Expression | Meaning |
| Yesterday | The day before today |
| Today | The current day |
| Tomorrow | The day after today |
| The day after tomorrow | Two days after today |
Imagine that today is Monday:
Sunday → Monday → Tuesday → Wednesday
- Sunday = yesterday
- Monday = today
- Tuesday = tomorrow
- Wednesday = the day after tomorrow
Example
If today is Monday:
I’ll call you tomorrow.
You mean Tuesday.
If you say:
I’ll call you the day after tomorrow.
You mean Wednesday.
Oxford and Cambridge both recognize the day after tomorrow as a normal expression.
Tomorrow vs. Today vs. Yesterday
The words yesterday, today, and tomorrow are closely connected.
They are useful because they refer to time relative to the speaker’s current day.
| Word | Basic meaning | Example |
| Yesterday | Day before today | I saw her yesterday. |
| Today | Current day | I am working today. |
| Tomorrow | Day after today | I will call her tomorrow. |
The important point is that their calendar references change.
Suppose today is September 26:
- Yesterday = September 25
- Today = September 26
- Tomorrow = September 27
On September 27, however, tomorrow will refer to September 28.
This type of word is sometimes described in linguistics as a deictic time expression because its interpretation depends on the time of speaking or writing.
Oxford’s entries for today and tomorrow also show their relationship as time expressions.
Can You Use Tomorrow With Will?
Yes.
Will + tomorrow is a common combination when talking about future actions.
Examples:
- I will call you tomorrow.
- She will arrive tomorrow.
- We will finish the project tomorrow.
- They will announce the results tomorrow.
However, tomorrow does not require will.
English has several ways to talk about future events.
Will
I will call you tomorrow.
Present continuous
I am meeting Sarah tomorrow.
Present simple
The train leaves tomorrow morning.
The present simple can describe future events when they are based on fixed schedules, timetables, or arrangements. Cambridge Grammar gives examples such as scheduled trains and other fixed future events.
So the following are all possible:
I will see you tomorrow.
I’m seeing you tomorrow.
The train leaves tomorrow.
The grammar changes, but tomorrow still identifies the relevant future day.
Common Grammar Mistakes With Tomorrow
Knowing the definition is only part of using the word correctly. Several common mistakes involve spelling, prepositions, and related expressions.
Mistake: Writing Tommorow
❌ I will see you tommorow.
✅ I will see you tomorrow.
Remember:
One M, two Rs.
Mistake: Writing Tomorow
❌ I will finish it tomorow.
✅ I will finish it tomorrow.
The second r should not be omitted.
Mistake: Using on before tomorrow
In standard everyday English, you normally say:
I’ll see you tomorrow.
not:
I’ll see you on tomorrow.
Compare this with a specific calendar date:
I’ll see you on Monday.
I’ll see you on September 27.
The time expression tomorrow normally works without on.
Mistake: Confusing tomorrow with the day after tomorrow
If today is Monday:
- Tuesday = tomorrow
- Wednesday = the day after tomorrow
Mixing these expressions changes the intended date.
Mistake: Confusing tomorrow and tomorrow’s
These forms have different grammatical roles.
I’ll finish it tomorrow.
I’ll finish tomorrow’s report.
The first identifies a time. The second modifies a noun.
Tomorrow Spelling Trick
If you repeatedly type tommorow, use this simple memory rule:
One M + two Rs = TOMORROW
Write it several times:
tomorrow
tomorrow
Then compare:
tommorow ❌
tomorrow ✅
Another useful way to remember the spelling is to notice the historical connection with morrow. Oxford gives the word origin as Middle English and explains that tomorrow developed from to + morrow.
That means the internal sequence can be remembered as:
to + morrow → tomorrow
Tomorrow Word Origin and Etymology
The history of tomorrow explains something about its unusual spelling.
Oxford identifies its origin as Middle English, originally written as two words and formed from the preposition to plus morrow.
The older word morrow refers to the following day or morning and now has a much more literary or old-fashioned feel in modern English.
Over time, the expression developed into the single modern word:
tomorrow
The historical structure is useful for learners because it helps explain why the word is not spelled tommorow.
Tomorrow Meaning in Different Contexts
The exact meaning of tomorrow depends on context.
Calendar context
Here, tomorrow means the specific calendar day immediately following today.
The store opens tomorrow.
Scheduling context
In appointments and plans, tomorrow identifies when something is scheduled.
The interview is tomorrow.
Future context
In broader discussions, tomorrow can mean the future.
We need to prepare for tomorrow.
Figurative context
Writers sometimes use tomorrow as a symbol of hope, change, possibility, or uncertainty.
A better tomorrow starts with good decisions today.
Cambridge explicitly includes the broader meaning of tomorrow as a time in the future, while Oxford gives examples involving future workers and a better future.
Tomorrow in Formal and Informal English
Tomorrow is completely normal in both formal and informal English.
Formal example
The committee will meet tomorrow to review the proposal.
Business example
The revised report will be available tomorrow morning.
Academic example
Students must submit their assignments by tomorrow.
Informal example
I’ll see you tomorrow!
The spelling does not change according to formality.
You should use tomorrow in professional emails, academic writing, text messages, conversations, reports, and everyday speech.
Idioms and Expressions With Tomorrow
The word tomorrow appears in several established expressions.
Like there’s no tomorrow
The expression like there’s no tomorrow means doing something excessively or without concern for its future consequences.
For example:
He spends money like there’s no tomorrow.
They danced like there was no tomorrow.
Cambridge and Oxford both list this idiom.
Jam tomorrow
Jam tomorrow is a British English expression referring to attractive benefits that are promised for the future but never actually arrive.
For example:
The employees were tired of promises of jam tomorrow.
Oxford identifies jam tomorrow as a British informal idiom.
Tomorrow is another day
This expression suggests that a difficult situation does not necessarily determine what will happen in the future.
For example:
Today was disappointing, but tomorrow is another day.
The phrase is often used to express hope or encourage someone to look beyond a difficult present moment.
Tomorrow in Everyday Conversation
Native and fluent English speakers use tomorrow constantly when arranging plans.
Here are natural examples:
Asking about plans:
Are you working tomorrow?
Making a promise:
I’ll call you tomorrow.
Making an arrangement:
We’re meeting tomorrow afternoon.
Discussing a deadline:
The application is due tomorrow.
Talking about uncertainty:
Who knows what tomorrow will bring?
Postponing something:
Let’s deal with it tomorrow.
The word is therefore much more useful than its basic dictionary definition might suggest. It appears in scheduling, planning, promises, deadlines, predictions, conversations, and discussions about the future.
Tomorrow in American and British English
The spelling tomorrow is standard in both American and British English.
The main difference is usually pronunciation, not spelling.
Cambridge provides UK and US pronunciations, while Oxford’s learner dictionaries likewise provide pronunciation information for different varieties of English.
There are also regional expressions involving tomorrow.
For example, Cambridge notes a week from tomorrow in American English and gives tomorrow week as a British usage.
For most English learners, however, the safest and most widely understood expression is:
a week from tomorrow
Case Study: Understanding Tomorrow With a Calendar
Imagine that today is Friday, September 26.
A student says:
My exam is tomorrow.
That means the exam is on Saturday, September 27.
Now imagine that the same student says:
My exam is the day after tomorrow.
That means the exam is on Sunday, September 28.
The meaning changes because the two expressions refer to different positions on the calendar.
| Relative day | Date in this example |
| Yesterday | September 25 |
| Today | September 26 |
| Tomorrow | September 27 |
| The day after tomorrow | September 28 |
This simple timeline is one of the easiest ways to understand the difference.
Case Study: Tomorrow as a Noun vs. Adverb
Consider these two sentences:
I will finish the report tomorrow.
Tomorrow will be difficult.
The same word appears in both sentences, but its grammatical role differs.
In the first sentence, tomorrow tells us when the action will happen. It functions as an adverb.
In the second sentence, tomorrow is the subject of the sentence. It functions as a noun.
This is a useful reminder that a word’s part of speech depends on how it functions in a sentence, not simply on the word itself.
Is Tommorow a Word?
Tommorow is not the standard spelling of the word.
If you are writing in standard English, use:
tomorrow
not:
tommorow
The difference is not semantic. Tommorow does not have a separate accepted definition that you should use in place of tomorrow. It is simply a spelling error.
For formal writing, schoolwork, professional communication, websites, and published content, always use tomorrow.
Is Tomorrow One Word?
Yes.
Tomorrow is normally written as one word.
Correct:
I’ll finish it tomorrow.
Incorrect:
I’ll finish it to morrow.
The modern English form is a single word, although its historical development involved the earlier elements to and morrow. Oxford records that historical origin.
What Is Another Word for Tomorrow?
There is no perfect everyday synonym for tomorrow.
Depending on the sentence, alternatives can include:
- the next day
- the following day
- the day after today
- a future day
However, these alternatives are not interchangeable in every situation.
For example:
I’ll call you tomorrow.
can become:
I’ll call you the next day.
But the second version may require a specific context to make it clear which day you mean.
In everyday conversation, tomorrow is usually the simplest and most natural choice.
Tomorrow Meaning in Urdu
For English learners who speak Urdu, tomorrow commonly translates as کل when referring to the day after today.
However, Urdu’s کل can refer to either yesterday or tomorrow, depending on context. English makes the distinction explicitly:
- yesterday = the previous day
- tomorrow = the following day
Cambridge’s English–Urdu Dictionary gives tomorrow as کل (آنے والا دن), clarifying the intended meaning as the coming day.
This distinction can be particularly useful for Urdu-speaking English learners.
