どっち（どっち、doっchi）
- which one

The word どっち means "which one" or "which way." It's used when asking a question about a choice between two things or options. It implies there are two possibilities presented or understood. どっち can refer to people, objects, directions, or any other set of two alternatives. It's a casual and common way to ask a question in Japanese.

⚫︎ Use どっち when you're presenting two choices. ⚫︎ It is very informal and is best used with friends, family, or in casual conversations. ⚫︎ Avoid using どっち in formal situations or with people you don't know well.
