notoriousyoudaoicibaDictYouDict[notorious 词源字典]
notorious: [16] Notorious originally meant simply ‘well known’. It was borrowed from medieval Latin nōtōrius, which was a derivative of nōtus ‘known’, the past participle of Latin nōscere ‘know’ (source also of English notice, notion, etc). The English word very soon came to be used in association with derogatory nouns (as in ‘a notorious liar’), and by the early 17th century the adjective itself had taken on negative connotations. (Noble, which comes from the same ultimate source and likewise etymologically means ‘known’, has gone up in the world as far as notorious has gone down.)
