Italian academia, in the hope of attributing a source, has over time accumulated unproven hypotheses found in Ancient Greek σκῐερός (skĭerós, “shady, dark coloured”) (in reference to the color of the lava stone) and a not better explained derivation from Latin flāgrō (“to burn”) (cfr. ciàguru for this latter).
