noun
furnishings; arrangements; setup
Refers to the way a room, space, or event is set up with furniture, decorations, or equipment; often implies a deliberate, aesthetic arrangement.
茶室のしつらえが美しい。
The tea room's furnishings are beautiful.
宴会のしつらえを整える。
Prepare the arrangements for the banquet.
準備 is general preparation, while しつらえ specifically refers to the physical setup or arrangement of a space.
装飾 is decoration or ornamentation, whereas しつらえ includes the overall layout and furnishing, not just decorative elements.
Derived from the verb しつらえる (to set up, to arrange), which is a compound of し (emphatic prefix) and つらえる (to arrange). The exact historical derivation is uncertain.
