Questions & Answers about A válvula do comboio a vapor avariou há muitos anos.
Why does this sentence use a vapor instead of de vapor for a "steam train"?
In Portuguese, the preposition a is used to describe the mechanism, energy source, or instrument that makes a machine work. Since the train is powered by steam, it is a comboio a vapor. If you used de, it would imply the train is literally made out of steam! You will see this same pattern in words like fogão a gás (gas stove) and barco à vela (sailboat).
If we were talking about multiple steam trains, would it be comboios a vapores?
Why use the verb avariou here instead of partiu for "broke down"?
Avariar specifically means to break down mechanically or to stop functioning. It is the perfect verb for machines, vehicles, and appliances. Partir means to physically shatter or snap into pieces, like a window or a bone. Since a valve is a mechanical part that stopped doing its job, avariou is the most natural choice.
Is há muitos anos the only way to say "many years ago"?
Using the verb haver in the third-person singular (há) is the standard and most natural way to express elapsed time ("ago") in Portugal. You are essentially saying "there are many years" since the event happened. While B2 learners sometimes try to directly translate "ago" by putting a word at the end of the sentence, in Portuguese the há always comes before the time period.
