Tonight or Tonite – Quick Answer

- Tonight → Standard spelling, used in books, newspapers, emails, and formal writing.
- Tonite → Informal variant, often seen in text messages, social media posts, advertising, or marketing.

The Origin of Tonight
The word “tonight” comes from Old English, originally written as “to niht”, meaning “on this night.” Over centuries, the two words merged into a single term.
- Middle English: “to-nyght”
- Modern English: “tonight”
The informal “tonite” emerged much later as a simplified, phonetic spelling. It is mostly seen in the 20th century, popularized by advertising, music, and texting culture. Linguists note that while “tonite” mimics how people pronounce the word, it has never been widely accepted in formal dictionaries.
British English vs American English Spelling
Interestingly, “tonight” is universally accepted in both British and American English, while “tonite” is considered nonstandard everywhere. There is no difference in formal usage between the UK and the US.
