1.
what floor; which floor; how many floors
An interrogative used to ask which story of a building something is on, or how many stories a building has.
何 (what, how many) + 階 (floor, story). Distinct from the homophone 何回 ('how many times'), which uses 回 (occasions).
Common collocations
- 何階ですか: What floor is it?
- 何階にある: on what floor is it?
- 何階建て: how many stories (tall)
- 何階まで: up to what floor
Watch out
In speech, 何階 (what floor) and 何回 (how many times) sound identical. Context usually resolves the ambiguity, but speakers sometimes clarify by saying 何階目 ('which floor') vs. 何回目 ('which time').
