Pronunciation

Forms

hideux (feminine hideuse, masculine plural hideux, feminine plural hideuses)[1] Old French hisdos, hydus (about 1140); the modern spelling hideux dates from 1273.[2][3] Anglo-Norman hidus, hidous, hisdus.[4]

Etymology

Its origin is disputed.[2][5] The usual view is that it was formed from Old French hisde (“horror, fright”) + -os, with the suffix that became -eux.[5][6][1] That noun is traditionally derived from Old High German *egisida (“horror”), a derivative of *egisōn (“to frighten”);[2][3] Wiktionary gives it as Proto-West Germanic *agisiþu (“horror, terror”), from *agisōn (“to frighten”).[1] The FEW files the word under the concept “to frighten”.[7]

Diez's older explanation takes it from Latin hispidōsus (“bristly, shaggy”), recorded in Catullus, a derivative of hispidus (“bristly, rough”).[5][2] Pierre Guiraud likewise derived the Old French noun itself from the Latin adjective, with an expressive initial ⟨h⟩;[2][3] Wiktionary notes that the change of sense is harder to explain on this view.[1]

Earliest recorded meaning

It is first recorded about 1140 as hydus in Geffrei Gaimar's Estoire des Engleis, meaning “inspiring horror”, “terrifying”.[5][2]

Semantic evolution

The word has kept much of its early force: from “inspiring horror” it came to mean “horrible to look at, repulsively ugly”, and in 1694 (Boileau) figuratively “morally revolting”.[2][6] It remains stronger than affreux or horrible, except in a weakened use for what merely offends good taste.[2]

The adverb hideusement is nearly as old (about 1185, hisdosement, “in a frightening way”).[2] Anglo-Norman hidus meant “terrifying, dreadful” and also “ugly”;[4] through it English took hideous about 1300, first in the sense “terrifying”, with “repulsive” from the late 14th century.[8]
