Did you know?

If you've ever trembled with fright, you know something of both the sensation and etymology of trepidation. The word comes from the Latin verb trepidare, which means "to tremble." Early meanings of trepidation, such as "tremulous motion" or "tremor," reflect that origin; those are followed by the word's sense of "apprehension."
