- ἰ̄ός 4
- ἰ̄ός 4.Grammatical information: m.Meaning: `rust' on iron, `verdigris' on copper, bronze (Thgn., Hp., Pl., Theoc., SIG 284, 15 [Chios IVa]).Derivatives: ἰώδης `rust-coloured' (Hp., Thphr.).Origin: XX [etym. unknown]Etymology: Given the changing meaning of IE *u̯ī̆s(o)- (s. on 3. ἰός) our word has been identified with it (Fick 23, 242). It could be due to different uses according to occupation; note, that ἰός `rust' as opposed to ἰός `poison' was used also in prose, what may point to a stilistic differentiation.Page in Frisk: 1,730-731
