AI-written, reviewed by AI (ChatGPT)
How to form it
- Verb (ます-stem, e.g. 食べ) + たい
- The ending conjugates like an い-adjective: ~たくない, ~たかった, ~たくなかった
- The object marker を is often replaced by が: 水が飲みたい / 水を飲みたい
Register: Neutral; add です for politeness
Explanation
Expresses a wish to do something.
In ordinary statements it most commonly describes the speaker's own wish (or the listener's, in a question). To describe another person's observable desire, ~たがる is often more natural; ~たい can also describe another person's wish when context or reported information supports it. Asking ~たいですか directly can sound blunt to a superior.

Common mistakes
- Saying 先生は行きたいです to report a third person's wish; ~たがっています or ~たいそうです is usually used instead.
- Using ~たい for a thing you want to have; use Noun + がほしい (本がほしい).
