Word Origin & History
ardent
c.1374, from O.Fr. ardant, from L. ardentem (nom. ardens), prp. of ardere "to burn," from PIE base *as- "to burn, glow" (cf. Skt. asah "ashes, dust," Arm. azazem "I dry up," Gk. azein "to dry up, parch," Goth. azgo, O.E. æsce "ashes," L. ardus "parched, dry"). The fig. sense (of passions, desire, etc.) was earliest in Eng.; literal sense of "burning, parching" (c.1440) remains rare. Ardent spirits (1471) "strong alcoholic liquor" so called because they are inflammable, but the term now, if used at all, probably is felt in the fig. sense.
