What is the origin of valorous?
Valorous comes from Late Latin valor “worth, honor,” a derivative of valēre “to be powerful.” The Latin noun comes from the Proto-Indo-European root wal-, which also appears in Tocharian B walo “king” (Tocharian A and B were spoken in the Tarim Basin, now part of Xinjiang Uygur, China, and died out about 1100 a.d.). The extended form wald- “strong, be strong” underlies English wield and the proper name Oswald (from os “god” and weald “power”). In Slavic wald- appears in the Polish personal name Włodzimierz, Old Russian Volodimĕr “(having) great power, famous.” Modern Russian Vladimir is based on Old Church Slavonic Vladiměrŭ. Valorous entered English in the 15th century.
