Etymology : The rare adjective riant is a direct borrowing from the French present participle riant ?laughing,? from the verb rire, ultimately from Latin r?d?re ?to laugh,? which comes from a very complicated Proto-Indo-European root wer- ?to twist, bend? (r?d?re would mean ?twist the face or mouth?). Wer- has many suffixes and extensions that form some startling words. The meaning of the root extended with the suffix -t is clearly seen in Latin vertere ?to turn,? with its many English derivatives, e.g., revert, convert, invert. The Germanic form of wert- is werth-, source of the English suffix -ward(s), as in homeward(s), toward(s). A variant form of wer- with the suffix -m forms Latin vermis ?worm? (from its twisting) and Germanic wurmiz (Old English wyrm ?dragon, serpent?; English worm). Finally, somewhat related to r?d?re is the Latin noun rictus ?wide open mouth, gaping jaws? (English rictus). Riant entered English in the 16th century.
