Questions & Answers about Nós estamos a construir um hospital enquanto vocês estão a construir um parque.
Does the word enquanto require a special verb tense after it?
Why do we use estamos a construir instead of the normal present tense construímos?
This is the Portuguese present continuous tense, used for actions happening right now. In European Portuguese, we form it with the verb estar plus the preposition a followed by the infinitive of the main verb (construir). It works exactly like the English 'are building'.
Could I drop the pronouns nós and vocês in this sentence?
You could easily drop nós because the verb estamos only ever belongs to 'we'. However, estão can mean 'they' or 'you all', so keeping vocês removes any guesswork. Furthermore, keeping both pronouns in this specific sentence strongly emphasizes the contrast between what 'we' are doing and what 'you' are doing.
I see the word hospital is spelled exactly like it is in English. Does it sound the same?
