Questions & Answers about A água do chuveiro está fria.
Why do we use está instead of é for "is" in this sentence?
Why is it água do chuveiro instead of chuveiro água for "shower water"?
In English, you can put two nouns together so the first one acts like an adjective (like "shower water"). In Portuguese, you cannot do this. Instead, you connect them with the preposition de (of). Here, de combines with the masculine word for "the" (o) to make do, literally meaning "the water of the shower".
Why does the word for cold end in an "a" (fria)?
Adjectives in Portuguese must match the gender of the noun they describe. Because água (water) is a feminine noun, the adjective must change from its default masculine form (frio) to the feminine form (fria).
Does chuveiro mean both the physical shower and the act of taking a shower?
No, chuveiro refers specifically to the physical plumbing fixture or the shower cabin. If you are talking about the act of washing yourself, you use the word banho, like in the phrase tomar banho (to take a shower or bath).
