atrocious

Etymology

It is from Latin atrōx (“fierce, cruel, gloomy”), in its stem form, with the suffix -ous.^{[2][3][4][5][6]} Dictionary.com instead derives it from the stem of atrocity.^[7] The Latin adjective is compounded of āter (“black, dark”) and an element -ōx (“looking”), so that it first meant dark-looking.^{[8][9][10][11]} That element is related to oculus (“eye”), and goes back to the same base as Ancient Greek ὤψ (ṓps, “eye”) and eye; it also occurs in ferōx (“fierce”), the source of ferocious.^[9][8] Merriam-Webster's Unabridged compares the word for black with Avestan ātar- (“fire”) and perhaps Welsh odyn (“kiln”).^[10]

Earliest recorded meaning

Of actions, wantonly cruel and heinously wicked: 1669, in A. Honyman's Survey Naphtali.^[2] Etymonline likewise has the 1660s, and Dictionary.com 1660–70, but Merriam-Webster's Unabridged gives 1604 as the first known use.^[3][7][10] Atrocity is older, from the 16th century.^[4][11]

Semantic evolution

The Latin word took "of a dark or threatening appearance" to "gloomy, cruel", and English borrowed it in the sense "wantonly cruel".^[9] Johnson (1755) defined it as "wicked in a high degree; enormous; horribly criminal", quoting Ayliffe on an atrocious offence.^[12] It was used of persons from 1772, in Pennant,^[2] and Darwin wrote in 1845 of "atrocious acts which can only take place in a slave country".^[11] The sense "stern, terrible, fierce" had a brief life in the 1730s.^[2][6] The word weakened in colloquial use to "very bad, execrable", of things like the weather or someone's English: the OED has it from 1779, Etymonline and the Shorter Oxford from the late 19th century.^{[2][3][6][11]} Atrocity has not weakened in the same way.^[11]
