noun — a palace; a temple hall
字源 FORM — what the parts do
宀義a roof — a great building
呂義two rooms, one above the other
A roof (宀) over rooms stacked room-on-room (呂) — a building of many chambers, the palace. The 呂 inside is two mouths of space linked, one opening into the next. The old graph carries two tellings of that 呂: the picture above, paired rooms; or, per 說文, 躳省聲 — the inner piece doing double duty as the sound as well.

一個屋頂（宀）下，房間一間接一間（呂），走不到頭。
One roof (宀), and under it room after room (呂) with no end in sight.
