köken: Borrowed from Latin Aetna, from either Ancient Greek Αἴτνη (Aítnē, “Aetna”) or αἴθω (aíthō, “to burn”), or from a Sicanian dialect Italic base *aith-na (“fiery one”), all from Proto-Indo-European *h₂eydʰ- (“burn; fire”).
köken: Latin Aetna, in turn from either Ancient Greek Αἴτνη (Aítnē, “Aetna”) or αἴθω (aíthō, “to burn”), or from a Sicanian dialect Italic base *aith-na (“fiery one”), all from Proto-Indo-European *ai-dh, from *h₂eydʰ- (“burn; fire”).
Aetna (nymph in Sicily) · Aetna (an ancient city in Sicily, in modern Italy, situated at the foot of Mount Etna)
köken: From Ancient Greek Αἴτνη (Aítnē, “Aetna”) or αἴθω (aíthō, “to burn”), or from a Sicanian dialect Italic base *aith-na (“fiery one”), all from Proto-Indo-European *ai-dh, from *h₂eydʰ- (“burn; fire”). Cognate with aestus (“hot”), aestās (“summer”).
köken: A tautological toponym from the Latin mons + Arabic جَبَل (jabal), both meaning “mountain”. It is not clear if the first element derives directly from Sicilian munti, from Latin mōns, montem or from another romance adstratum; in any case, the last syllable dropped unusually in favour of the palatalization with the second compound word.
