屋敷
やしき · yashiki · JLPT N1 · noun
sign of the zodiac
屋 — corpse 尸 + reach/arrive 至
屋 originally depicted a place where one arrives (至) to rest under a roof, with 尸 here representing a covering or dwelling rather than a corpse. The character came to mean 'house' or 'room'. Today it commonly refers to a house or a room within a building.
敷 — 尃 (fū, phonetic) + 攵 (action)
敷 is a semantic-phonetic compound. The right side 攵 (a hand holding a stick) suggests an action, while 尃 supplies the sound and the idea of spreading or distributing. The original sense was to spread out or apply broadly, which extends to modern meanings like 'to apply' (ointment) or 'to lay out'.
