楼房
loú fáng · HSK 6
a building of two or more stories
🏢 楼房 = floor/story + room — a room stacked into floors
楼 means floor or story (as in a multi-level structure), 房 means room or house. Together they specify a building with multiple stories — not a single-floor dwelling but one where rooms are stacked vertically. Lou sounds like 'Lou Reed climbing stairs.'
楼 — wood radical 木 + 婁 (lóu, phonetic)
楼 is a phono-semantic compound. The 木 radical signals wood, fitting a multi-storied wooden building, while 婁 supplies the lóu sound. Originally written 樓, it referred to a tower or upper story, and today means a multi-floor building or a specific floor.
