Forms

terribilis (neuter terribile, comparative terribilior, adverb terribiliter); third-declension two-termination adjective[1]

Etymology

It is from Latin terreo (“to frighten”) + -bilis.[2][1] terreō continues Proto-Italic *trozeō, from Proto-Indo-European *troséyeti, from Proto-Indo-European *tres- (“to tremble”).[1]

Earliest recorded meaning

Köbler dates its first use to Ennius, 204–169 BC.[3] Cicero says of a man “how terrible to look at!”.[4][5]

Semantic evolution

It meant inspiring terror or alarm, frightening, of persons, faces, sounds, shouts or death.[2][6] Livy says a people's arms were the most feared after the Gallic invasions, and Virgil's Aeneas is terrible in his anger.[6][4] Gaffiot also gives the sense worthy of respect, venerable.[5]

In Christian and medieval Latin it meant awe-inspiring, holy, and death was the ultimum terribilium “the last of terrible things”.[3][7] English terrible is recorded around 1400, from Old French and Latin.[8]
