rugină

== Romanian == === Etymology === Probably from Vulgar Latin *aerūgina, from Latin aerūgō, aerūginem (“copper rust”), with a later stress shift to the penultimate syllable in Romanian, which may have occurred due to the influence of derivatives such as rugini, ruginos, etc. Compare Italian ruggine, Friulian ruzin; cf. also Asturian roña. Alternatively, and less likely, from Latin rūbīginem, accusative of rūbīgō (“rust”), also with a stress shift; compare Spanish robín. Cognate to Aromanian arudzinã. === Pronunciation === === Noun === rugină f (plural rugini) rust ==== Declension ==== ==== Derived terms ==== === References ===
