From Latin vitrum.


vitrum (plural vitra)

  1. (obsolete) Glass; a glassy material.
    • 1665, Robert Hooke, Micrographia:
      I imagine it to be some small parcel of the Steel, which by the violence of the motion of the stroke […] is made so glowing hot, that it is melted into a Vitrum, which by the ambient Air is thrust into the form of a Ball.



From Proto-Italic *wedrom (glass), from Proto-Indo-European *wed-ro- (water-like), from *wed- (water) (whence also Latin unda (water)). Compare semantic parallel in Middle Iranian where "glass" is also derived from "water": Middle Persian ʾp̄ḵynk' (ābgēnag, crystal, glass), compound of ʾp̄ (āb, water) + -kyn' (-gēn) + -k' (-ag) > Persian آبگینه(âbgina, glass), Sogdian ʾʾpkyn-, ʾʾpkynʾk (crystal), Ossetian авг (avg) (Iron) / авгӕ (avgæ, glass; bottle) (Digor). Compare also Old Armenian ապակի (apaki) and Hungarian üveg (glass; bottle). The plant and its dye were named after the color of glass in antiquity.
