glass (English)
Where does "glass" come from?
The English noun 'glass' comes from Middle English 'glas'[1][2], which developed from Old English 'glæs'[1][3]. This word traces back through Proto-West Germanic '*glas'[1][5] to Proto-Germanic '*glasą'[1][4]. The Germanic noun is closely connected to concepts of radiance, being related to the verb '*glōaną' meaning 'to shine' or 'to glow'[1][4]. Ultimately, the term derives from an ancient Proto-Indo-European root meaning 'to shine, shimmer, glow'[1][3][4].

- Scholars debate the exact pathway into Proto-Germanic, specifically whether '*glasą' derives directly from an Indo-European root extension or formed as an s-stem noun from the Germanic verb '*glōaną'. [1] [4]
