roña f (plural roñes)

1. grime, dirt
2. rust

From Latin aerūgō, aerūginem (“rust”), from aes, aeris (“bronze”) +‎ -ūgō (forms nouns denoting superficial coatings). Or maybe linked to a Vulgar Latin *ronea or *aronea, from Latin arānea (“spiderweb”) (perhaps with influence from another word, such as rōbīgō (“rust”), rubea (“reddish”), or rōdō (“gnaw”)), and thus would be a doublet of araña. Compare Portuguese ronha, Galician raña, Catalan ronya, French rogne, Italian rogna, Sicilian rugna; cf. also Romanian râie.
