English[edit]

Etymology[edit]

From Latin vitrum.

Noun[edit]

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.

Latin[edit]

Latin Wikipedia has an article on:

poculum ex vitro.

Etymology[edit]

Nominalised from Proto-Indo-European *wed-ro- (literally “water-like”),[n 1] from the root *wed- (“water”).[1][2] For the semantic development compare Persian آبگینه (âbgina, “glass”). The plant and its dye were named after the color of glass in antiquity.

Notes[edit]

  1. ^ Both the shift of PIE *-dr- to Latin -tr- (cf. lutra, uter) and of *we- to vi- (cf. vigeō, vitulus) are expected.
