ガラス · garasu · JLPT N4 · noun
glass
🪟 From Dutch glas: garasu is just glass with Japanese vowels added
A loanword from Dutch glas, brought by traders in the Edo period. Japanese cannot stack g+l or end on s, so it became ga-ra-su. It means the material or a pane; a drinking glass is a different loan, gurasu (グラス), from English.
