WEBSTER'S Word of the Day "candor" (12/06/2017)
Definition
1 : whiteness, brilliance
2 : freedom from prejudice or malice : fairness
3 : unreserved, honest, or sincere expression : forthrightness
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.
