Etymology

Origin of terrify

1565–75; < Latin terrificāre, equivalent to terr ( ēre ) to frighten + -ificāre -ify

Explanation

If you terrify someone, that person is enormously frightened of you. The verb terrify is closely related to the word terror, and its Latin root is terrificus, "causing terror." While some people might say that monsters terrify them, others are terrified by heights, snakes, or speaking in public. If there's something that makes you feel a deep, horrible sense of fear, it terrifies you.
