📜 What does "das Glas" mean?

Das Glas is a versatile German word with several main meanings:

  • Drinking glass: The most common meaning. A container, usually made of Glas (glass), used for drinking. Example: Bitte gib mir ein Glas Wasser. (Please give me a glass of water.)
  • Material: The hard, brittle, transparent substance itself. Example: Das Fenster ist aus Glas. (The window is made of glass.)
  • Unit/Quantity: Refers to the contents of a drinking glass. Example: Ich trinke jeden Morgen ein Glas Orangensaft. (I drink a glass of orange juice every morning.)

In plural, 'die Gläser' is often synonymous with 'die Brille'. Example: Mein rechtes Brillenglas hat einen Kratzer. (My right eyeglass lens has a scratch.)
  • Pane of glass: A flat sheet of glass, e.g., in a window or door. Example: Die Einbrecher haben ein Glas eingeschlagen. (The burglars broke a pane of glass.)

✒️ A Short Poem about das Glas

Das Glas, so klar und rein,
hält Wasser, Saft und Wein.
Zerbrechlich ist's, gib acht,
sonst ist's schnell entzwei gemacht.
Durchs Fenster scheint die Sonn' herein,
durch Glas, so hell und fein.

The glass, so clear and pure,
holds water, juice, and wine, secure.
It's fragile, take care,
or it's quickly broken beyond repair.
Through the window, the sun shines in,
through glass, so bright and thin.
