a fragrant shrub noted for its beauty and its thorns, cultivated from remote antiquity, Old English rose, from Latin rosa (source of Italian and Spanish rosa, French rose; also source of Dutch roos, German Rose, Swedish ros, Serbo-Croatian ruža, Polish róża, Russian roza, Lithuanian rožė, Hungarian rózsa, Irish ros, Welsh rhosyn, etc.), probably via Italian and Greek dialects from Greek rhodon "rose" (Aeolic brodon).
Greek rhodon probably is ultimately from or related to the Iranian root *vrda-. Beekes writes that "The word is certainly borrowed from the East, probably like Arm[enian] vard 'rose' from OIran. *urda." Aramaic warda is from Old Persian; the modern Persian cognate, via the usual sound changes, is gul, source of Turkish gül "rose."
The form of the English word was influenced by the French. Used as a color name for a light crimson by 1520s (earlier rose-color, late 14c.; rose-red, early 13c.). As "person of great beauty or virtue," early 15c. A rose-bowl (by 1887) is one designed to hold cut roses.
