rugiada

Etymology
Ultimately from but borrowed, at least in the form, from some  language. The form in question is first documented in the late thirteenth century, as are both of the more indigenous-looking variants above.

As ⟨VgiV⟩ has since the late thirteenth century in Tuscany denoted [ʒ] (later 'corrected' to [d͡ʒ] in Standard Italian), ⟨rugiada⟩ would be the expected spelling for a pronunciation like [ruˈʒaːda]. As it happens, [ʒ] is a common intervocalic outcome of Latin [s] in Gallo-Italic, for instance in the modern dialects bordering northeastern Tuscany.
