vitrum

vitrum Glas

• Perhaps from Proto-Indo-European *wed-ro- (literally “water-like”), from the root *wed- (“water”).
• Or, from a substrate source in common with Proto-Germanic *waizdaz and Ancient Greek ἰσάτις (isátis, “woad”).
• For the semantic development compare Persian آبگینه (âbgina, “glass”). The plant and its dye were named after the color of glass in antiquity.
