Hello! My question is, why the name of the isle of Sardinia is Cerdeña in Spanish? I can imagine that the first Spanish visitors of Sardinia were "ceceantes", i.e. pronouncing "s" like "z" (or "c" before the vowels e/i). Neverthless, I don't understand the vowel "e" instead of "a" (i.e. why not *Zardeña). However, this name is a bit curious to me, because I should expect some "re-correction" resulting in a common Sardeña/Sardiña or even Sardinia. Thanks in advance.
