Ра́дуга

Etymology

edit

Inherited from Proto-Slavic *radǫga. The first element more likely derives from Proto-Slavic *radъ (glad, dear, willing) than folk etymology’s Proto-Slavic *rajь. Compare Russian весёлка (vesjólka, rainbow) (dialectal) related to весёлый (vesjólyj, merry, cheerful, happy, convivial, gleeful, lighthearted), Belarusian вясёлка (vjasjólka, rainbow). The second element from Proto-Slavic *dǫga would be cognate with Lithuanian dangùs (sky, heaven) and perhaps further Proto-Germanic *tunglą (heavenly body) together from a tentative Proto-Indo-European root *denǵʰ-.

Slavic cognates include Ukrainian ра́йдуга (rájduha).

A borrowing from Old Ossetic *ardunga- cognate with Classical Persian درونه (durōna, rainbow) etc. is also possible.
