Questions & Answers about O vinho está na cave.
Wait, cave looks exactly like the English word cave. Does it mean the wine is in a literal cave?
No, this is a classic false friend. In Portuguese, cave means cellar or basement. If you wanted to talk about a natural cave (like where bats live), you would use the word gruta or caverna.
Why do we use está here instead of é?
Where does the word na come from?
It is a mandatory contraction of the preposition em (meaning in, on, or at) and the feminine word for the (a). Because cave is a feminine noun, in the cellar becomes em + a = na cave.
