Here's a breakdown:
* Anata (あなた) means "you". It's a polite way to address someone.
* Wa (は) is a particle that marks the topic of the sentence. It emphasizes "you" as the subject.
Examples:
* Anata wa kirei desu. (あなたは綺麗です。) - You are beautiful.
* Anata wa nani ga suki desu ka? (あなたは何がすきですか？) - What do you like?
* Anata wa koko de nani o shite imasu ka? (あなたはここで何をしていますか？) - What are you doing here?
Important Note: While "anata" is polite, it's not always used. In informal settings, people might use "kimi" (きみ) or "omae" (お前) to address someone. "Kimi" is slightly less formal than "anata," while "omae" is very informal and can be considered rude in some situations.
