paranoia

Etymology and origin of the English word paranoia

Pronunciation

  • IPA: /ˌpæɹ.əˈnɔɪ.ə/ (UK); /ˌpæɹ.əˈnɔɪ.ə/, /ˌpɛɹ.əˈnɔɪ.ə/ (US)[1]

Etymology

It is borrowed from New Latin paranoia,[2][3][4] from Ancient Greek παράνοια (paránoia, “madness, derangement”),[5][2][6][3][7] from paránoos “demented, distracted”,[5][2][6][3][7][4] from Ancient Greek παρά (pará, “beside, beyond”) + νόος (nóos, “mind”).[5][2][6][3][7]

Earliest recorded meaning

Mental derangement (1811, in the form paranoea).[8][2][6][3]

Semantic evolution

The modern form paranoia appears in 1848 in Etymonline and 1891 in Barnhart.[6][2] In psychiatry it came to mean a chronic disorder marked by systematized delusions, especially of persecution or grandeur,[6][8][5][3] and in general use extreme or irrational distrust of others.[5][3][9] Middle English medical writing had already described a pathological state of suspiciousness as suspecioushed (early 15th century).[6] The adjective paranoid dates from 1904.[2]
