vitrum

== English == === Etymology === From Latin vitrum. === Noun === vitrum (plural vitra) (obsolete) Glass; a glassy material. == Latin == === Etymology === 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”). (Can this(+) etymology be sourced?) For the semantic development compare Persian آبگینه (âbgina, “glass”). The plant and its dye were named after the color of glass in antiquity. === Pronunciation === (Classical Latin) IPA(key): [ˈwɪ.trũː] (modern Italianate Ecclesiastical) IPA(key): [ˈviː.trum] === Noun === vitrum n (genitive vitrī); second declension glass Synonym: hyalus dyer's woad, a plant used for dying blue (Isatis tinctoria) Synonyms: glastum, isatis woad, a blue dye used by the Britons made from that plant ==== Declension ==== Second-declension noun (neuter). ==== Derived terms ==== ==== Descendants ==== (See also the descendants of vitreus, which seems to be the source of mass nouns meaning 'glass' in a number of West Iberian languages.) === Notes === === References === === Further reading === “vitrum”, in Charlton T.
