It is from Latin terreō (“to frighten”) + -ficus,[2] a compound of terreō and faciō “to make”.[3][4][5]

Earliest recorded meaning

Lucretius, describing the Curetes, speaks of their terrifying crests.[3][6] Köbler dates Lucretius 96–55 BC.[7]

Semantic evolution

It meant causing terror, frightening, awe-inspiring, and was mainly poetic.[2][3] Ovid uses it of Jupiter's terrifying hair, Virgil of prophets, and Valerius Flaccus of a rite.[3] In prose Pliny the Younger speaks of frightening prophecies, and Gellius of a terrifying roar.[3][4]

British medieval writers used it of terrifying commands.[8] English terrific is recorded in the 1660s, in Milton, as “frightening”; its sense “excellent” dates from 1888.[5]
