الروديوم=rhodium

ONLINE ETYMOLOGY DICTIONARY:

rhodium (n.)

hard white metallic element, 1804, named for the color of solutions containing it, from Gk. rhodon "rose" (see rose (n.)) + metallic element ending -ium.

rose (n.)

O.E. rose, from L. rosa (source of Italian and Spanish rosa, French rose; also source of Dutch roos, German Rose, Swedish ros, etc.), probably via Italian and Greek dialects from Gk. rhodon "rose" (Aeolic wrodon), ultimately from Persian *vrda-. But cf. Tucker: "The rose was a special growth of Macedonia & the Thracian region as well as of Persia, & the Lat. & Gk. names prob. came from a Thraco-Phrygian source." Aramaic warda is from O.Persian; the modern Persian cognate, via the usual sound changes, is gul, source of Turk. gül "rose." The ultimate source of all this may be PIE *wrdho- "thorn, bramble."
