か can mark a polite question at the end of a sentence or connect alternatives inside it. 学生ですか asks a question; お茶か水 names a choice between tea and water. The position of か tells you which role it has.
Formation and use
For a basic polite yes/no question, add か to the polite predicate: 行きますか, 学生ですか. Japanese word order does not need the English-style subject-verb inversion.
A question word can appear with the same ending: 何を食べますか. Its answer supplies the requested information rather than only はい or いいえ.
Comparisons and common errors
Between alternatives, か means “or”: お茶か水をください. A contrast with と matters: お茶と水 requests both rather than one alternative.
In casual speech, questions can use rising intonation without か. A plain ending plus か can sound abrupt in some settings. Start with the polite model instead of assuming か always makes a sentence courteous.
