bronzo.

Attestions begin in northern Italy, and include bronzo in a Latin context in Liber consuetudinum Mediolani (1216); Lombard bronz, bronzo in Liber di Tre Scricciur, 1274; Venetan brondi ? in a semi-Latin document from Verona, 1339. Immediately, possibly from Latin *brundium, or directly from Latin brandisium (var.: bra/-i/-o), attested in recipes of bronze from the 8th-9th centuries CE. Related to Byzantine Greek βροντησίον (brontēsíon, “bronze”) (11th century), also from alchemy books. Several theories exist for the earlier stages: *The Greek has long been derived from Βρεντέσιον (Brentésion, “Brindisi”), known for the manufacture of bronze, or perhaps through a Vulgar Latin *aes brundusi(um), from the name of the same city. *Alternatively from βροντή (brontḗ, “thunder”), via Byzantine Greek developments, due to the use of the metal in noise and sound producing devices. Or a related onomatopoeic theory, connecting may sonorous objects under the one family. * More recently the Italian has been connected ultimately with Persian برنج (berenj, beranj, “brass”) ~ پرنگ (pereng, “copper”), * Among western languages, perhaps from Lombardic brunst (“burning, fire”), from Proto-Germanic *brunstiz, related to German Brunst, English burn. Less likely linked to Germanic through a Late Latin or Vulgar Latin *brunitius, related to Italian bruno (“brown”) and bruniccio (“brown”). Reborrowed as Renaissance Latin bronzium, from the early 1400s.
