Etymology and origin of the Ancient Greek word νόσος
- Confidence
- Unknown
- First attested
- Homer, Iliad
Pronunciation
Forms
νόσος (nósos) f (genitive νόσου); second declension[1] Epic and Ionic νοῦσος (noûsos).[2][3]
Etymology
There is no good etymology.[4][5] Homer and Herodotus have νοῦσος (noûsos), but Herodotus always uses νοσέω (noséō), so his use of it is probably a Homerism.[4][5] A pre-form *νόσϝος (*nóswos) would account for the forms,[4][5] but Wackernagel took the Homeric form as a miswriting of a *νόσσος (*nóssos).[4][5]
Willi derived it from Proto-Indo-European *n-h₁osu-o- (“not good”), comparing Hittite āššu- (“good”), but Beekes and Wiktionary point out that the regular outcome would be *anoswo-, and reject it.[4][1] Babiniotis tentatively connects it with νότιος (nótios, “moist”).[6]
Earliest recorded meaning
In the first lines of the Iliad Apollo sends a plague on the army: νοῦσον ἀνὰ στρατὸν ὦρσε κακήν “he raised an evil sickness through the host”.[2][7]
Semantic evolution
Hesiod uses it for the grievous diseases loosed on mankind and for distress in general.[2][3] In tragedy it is also madness sent by the gods, the sickness of love, and disorder in the state,[3][2] and Plato calls an unjust man a plague.[3][2] Herodotus calls epilepsy the sacred disease, and Galen gives a definition of disease.[2]
It survives as Modern Greek νόσος (nósos), a learned word in medieval and modern times.[8][9] English noso-, in medical terms, comes from it.[10]
