Pronunciation

  • /əˈtɹɒsɪti/, /əˈtɹɑsɪti/[1]

Etymology

It is borrowed from Latin atrōcitās (“cruelty, fierceness, harshness”),[2][3][4][5] a noun of quality from atrōx (“fierce, cruel, frightful”),[2][3] perhaps through the influence of Middle French atrocité,[4][2] which Merriam-Webster Unabridged, Klein and Skeat give as the direct source.[6][7][8] Barnhart explains atrōx as originally "having a gloomy face", from the stem of āter (“black, dark”) and a lost noun meaning eye or face;[4] Etymonline likewise reconstructs Proto-Indo-European *atro-ek-, from *ater- (“fire”) and *okw- (“to see”), hence "of fiery or threatening appearance".[3] The American Heritage Dictionary places the Latin adjective under the same root.[9] The adjective atrocious, from the same Latin stem, followed in the 1660s.[3][4]

Earliest recorded meaning

Savage enormity, horrible or heinous wickedness: 1534, in Thomas More's Treatice upon the Passion.[2][4]

Semantic evolution

The word first named a quality, extreme wickedness or cruelty;[2][3] Johnson (1755) defined it as "horrible wickedness; excess of wickedness".[10] From 1641 it was also used for fierceness or sternness, a sense now archaic.[2][11] The countable sense, an atrocious deed, an act of extreme cruelty, dates from 1793, in a letter of Thomas Jefferson;[2][3] modern dictionaries apply it especially to cruelty against civilians or prisoners in war.[12][9] From 1878 the word was used colloquially with no moral weight, for a bad blunder or an offence against taste or manners,[2] and Merriam-Webster Unabridged gives an ugly hat as an example of such an atrocity.[6]
