## Etymology
From Middle English glas, from Old English glæs, from Proto-West Germanic *glas, from Proto-Germanic *glasą, possibly related to Proto-Germanic *glōaną (“to shine”) (compare glow), and ultimately from the Proto-Indo-European root *ǵʰleh₁- (“to shine, shimmer, glow”).
Cognate with West Frisian glês, Dutch glas, Low German Glas, German Glas, Swedish glas, Icelandic gler.
