Did you know?
The origins of "candor" shine through in its first definition. "Candor" traces back to the Latin verb "candēre" ("to shine or glow"), which in turn derives from the same ancient root that gave the Welsh language "can," meaning "white," and the Sanskrit language "candati," which translates to "it shines." Other descendants of "candēre" in English include "candid," "incandescent," "candle," and the somewhat less common "candent" and "candescent" (both of which are synonyms of "incandescent" in the sense of "glowing from or as if from great heat"). There is even "excandescence ," an uncommon word that refers to a feverish condition brought on by anger or passion.
