📝 Usage Notes
must do; need to; gotta do
📖 How to use it
A casual spoken contraction of なくては (いけない) meaning 'must do' or 'gotta do'.
Attaches to
Attach to the negative ない-stem of a verb (the form that ない attaches to). For example, 行く -> 行かない -> 行かなくちゃ. For する, use しなくちゃ; for くる, use こなくちゃ.
なくちゃ is a short, casual way to say you have to do something. It comes from なくては, but in everyday conversation people drop the ては and just say なくちゃ. You often add いけない or だめ at the end, but when you use なくちゃ alone, it already means 'must' or 'gotta'.
もう行かなくちゃ。
Mō ikanakucha.
I gotta go now.
宿題をしなくちゃ。
Shukudai o shinakucha.
I have to do my homework.
水を飲まなくちゃ。
Mizu o nomanakucha.
I need to drink water.
Not なくては (いけない)
なくては is more formal and often used in writing or polite speech. なくちゃ is casual and used only in speaking with friends or family.
Register
