Questions & Answers about Comprar o palácio é um capricho fútil.
How would I change this sentence to mean "Buying the palace is such a frivolous caprice"?
Why is comprar used here instead of a gerund for "buying"?
In Portuguese, the impersonal infinitive (comprar) is used when a verb acts as the subject of a sentence. English uses the gerund ("-ing" form) for this, but Portuguese almost never uses its gerund (comprando) as a noun.
Is fútil a false friend here? Does it mean "futile" or "doomed to fail"?
Yes, it is a partial false friend. While it can mean "futile" in the sense of being pointless, it is much more commonly used in Portuguese to mean "frivolous", "superficial", or "shallow". A capricho fútil is a superficial whim, not necessarily a doomed one.
What is the plural of fútil if we were talking about multiple whims (caprichos)?
