店屋
みせや · miseya · JLPT N2 · noun
shop
🏪 店 (mise) = shop + 屋 (ya) = house: a shop-house, which is a store
屋 (ya) means house or dwelling, as in 屋根 (roof) and 八百屋 (greengrocer). Put them together and you get a house that is a shop, so a store.
店 — 广 (shelter radical) + 占 (zhān, phonetic)
店 is a semantic-phonetic compound. The radical 广 depicts a roof or open shelter, suggesting a building, while 占 supplies the sound (zhān → diàn). Originally it referred to a roadside inn or stall set up under a shelter, and over time the meaning narrowed to 'shop' or 'store'.
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.
