Etymology
Compare Ancient Greek σίδηρος (sídēros, “iron”). Some derive this from Proto-Indo-European *sweyd- (“sweat”), whence Latin sūdor, Ancient Greek ἱδρώς (hidrṓs), English sweat; however there are phonetic problems, most notably the initial /s/ in Greek instead of expected */h/. The origin of both the Latin and Greek words is unknown, but likely substrate and related to Pre-Greek.
