atrociousyoudaoicibaDictYouDict[atrocious 词源字典]
atrocious: [17] Traced back to its ultimate source, atrocious meant something not too dissimilar to ‘having a black eye’. Latin āter was ‘black, dark’ (it occurs also in English atrabilious ‘melancholic’ [17] – Greek mélās meant ‘black’), and the stem *-oc-, *-ox meant ‘looking, appearing’ (Latin oculus ‘eye’ and ferox ‘fierce’ – based on ferus ‘wild’, and source of English ferocious – were formed from it, and it goes back to an earlier Indo-European base which also produced Greek ōps ‘eye’ and English eye).

Combined, they formed atrox, literally ‘of a dark or threatening appearance’, hence ‘gloomy, cruel’. English borrowed it (in the stem form atrōci-) originally in the sense ‘wantonly cruel’.

boastyoudaoicibaDictYouDict
boast: [13] The immediate source of boast appears to be Anglo-Norman bost, but where it came from before that is far from clear; German dialect bauste(r)n ‘swell’ has been compared, suggesting that it could be of Germanic origin. To begin with it meant ‘loud or threatening talk’ as well as ‘bragging’.
menaceyoudaoicibaDictYouDict
menace: [13] Latin mināx meant ‘threatening’ (it was formed from a base *min- ‘jut’ which also produced English eminent and prominent, and hence etymologically denoted ‘overhanging’). From it was derived the noun minācia ‘threatening things’, which passed into English via Old French manace. The closely related demeanour comes ultimately from a word denoting ‘drive animals with threats’.
