WORD ORIGIN
late 16th cent. (originally meaning a legislative body in the Middle East): via French or Italian from Turkish dīvān , from Persian dīwān anthology, register, court, or bench. As a piece of furniture, a divan was originally (early 18th cent.) a low bench or raised section of floor against an interior wall, used as a long seat and common in Middle Eastern countries; European imitation of this led to the sense low flat sofa or bed (late 19th cent.).
