Origins

Proto-Indo-European *wed-der. Proto-Indo-European *wedrom Proto-Italic *wedrom? Latin vitrum Perhaps from Proto-Indo-European *wed-ro-m (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.
