zeitgeist (n.)

1848, from German Zeitgeist (Herder, 1769), "spirit of the age," literally "time-spirit," from Zeit "time" (from Proto-Germanic *tidiz "division of time," from PIE root *da- "to divide") + Geist "spirit" (see ghost (n.)). Carlyle has it as a German word in "Sartor Resartus" (1840) and translates it as "Time-Spirit."
