The word for glass in Spanish is vidrio.
When referring to a drinking glass, you would use the term vaso. For example, if you want to ask for a glass of water in Spanish, you would say, ¿Me puede dar un vaso de agua? which translates to ‘Can you give me a glass of water?’
It’s important to understand the context. ‘Vidrio’ refers to the material itself, while ‘vaso’ refers to the object that you drink from. Knowing the difference will help you communicate more effectively in Spanish.
