Quick Answer
Tonight is the correct standard spelling.
Tonite can appear as an informal alternative, especially in American entertainment and advertising contexts. It should not normally replace tonight in formal or professional writing.
Cambridge Dictionary lists tonight as a standard English word meaning the night of the present day.
Meaning of Tonight
Tonight refers to the night or evening of the current day.
It can work as an adverb or noun.
As an adverb:
- We are going to dinner tonight.
- I will finish the report tonight.
- The concert starts tonight.
As a noun:
- Tonight is the perfect time to relax.
- I am looking forward to tonight.
- The event is scheduled for tonight.
Cambridge Dictionary identifies tonight as both a noun and an adverb.
Meaning of Tonite
Tonite is sometimes used as an informal spelling of tonight.
It keeps the same pronunciation and usually carries the same intended meaning when used this way.
For example:
- See you tonite.
- The show starts tonite.
- Movie night is tonite.
However, tonite has another dictionary meaning. Merriam Webster defines tonite as the name of an explosive compound.
Collins also lists tonite as an explosive used in quarrying.
So context matters when you encounter this spelling.
Tonight vs Tonite Comparison
| Feature | Tonight | Tonite |
|---|---|---|
| Standard spelling | Yes | No, when meaning tonight |
| Meaning | The current day’s night | Informal spelling of tonight |
| Pronunciation | /təˈnaɪt/ | Usually the same |
| Formal writing | Recommended | Avoid |
| Academic writing | Recommended | Avoid |
| Professional writing | Recommended | Avoid |
| Casual messages | Recommended | Possible |
| Advertising | Common | Sometimes used for style |
| Entertainment | Common | Sometimes used for a casual style |
The safest choice is tonight because it is the established standard spelling across ordinary English usage.
Why the Confusion Exists
The confusion mainly comes from pronunciation.
The ending of tonight sounds like nite, which is an informal spelling associated with night. This can make tonite look like a natural shortened form.
The spelling also appears in casual advertising and entertainment contexts. Linguistic references describe forms such as nite and tonite as informal American spellings that have been used in advertising.
Text messaging and casual online communication can also encourage shortened spellings.
That does not make tonite the best choice for standard writing.
Dictionary Recommendations
Major dictionaries clearly support tonight as the standard word for the current day’s night.
Cambridge Dictionary defines tonight as the night of the present day and gives examples such as “What are you doing tonight?”
Merriam Webster has a separate entry for tonite, but its main definition is the explosive compound rather than the ordinary meaning of tonight.
Wiktionary records the informal use of tonite as an alternative spelling of tonight, particularly in US entertainment contexts.
This evidence makes the writing recommendation straightforward. Use tonight when you need the standard English spelling.
Origin of Tonight
The word tonight has a long history in English.
Etymology sources trace it to Old English toniht, formed from elements related to to and night. It referred to the present or coming night.
The spelling changed over time. Historical forms included separate words and later to-night before the modern single-word form became established.
This history explains why today’s spelling may not look exactly like its older forms.

When Tonite Can Be Used
Tonite can work when the unusual spelling is intentional.
It may appear in:
- Casual text messages.
- Informal social posts.
- Entertainment advertising.
- Posters.
- Headlines with a deliberately casual style.
- Brand names or creative campaigns.
The spelling can create a shorter or more relaxed visual style. Wiktionary specifically notes its use in US entertainment contexts.

Common Mistakes
One common mistake is assuming that tonite is the standard shortened form of tonight.
It is better to treat it as an informal variant rather than the normal spelling.
Another mistake is using tonite in formal documents because it sounds exactly like tonight.
Pronunciation does not determine standard spelling.
A third mistake involves the dictionary meaning of tonite. In some dictionaries, it refers to an explosive rather than an informal version of tonight.
Memory Trick
Use this simple rule:
Tonight has night inside it.
Think:
to + night = tonight
The word night helps you remember the standard spelling.
If you are unsure, choose tonight. It works in both casual and formal situations.
Professional Writing Recommendation
For almost every normal writing situation, use tonight.
It is the safest option for readers, editors, teachers, employers, and professional audiences.
Use tonite only when the informal style is deliberate and fits the context. If you are learning English or improving your standard writing, remember tonight as the preferred form.
