Questions & Answers about O guia insiste em que usemos o respirador por causa do mofo.
Why do we need em before que in this sentence? Can't we just say insiste que?
The verb insistir requires the preposition em to express insisting on something. In European Portuguese, when a verb requires a preposition, that preposition is kept even when it introduces a full clause starting with que. Therefore, you get insiste em que.
Why is usar conjugated in the subjunctive (usemos) instead of the indicative (usamos)?
The verb insistir expresses a demand or strong recommendation. Whenever you use a verb of influence, request, or will directed at someone else, it triggers the subjunctive mood in the following que clause.
I know porque means because. Why does the sentence use por causa do instead?
Why does por causa de change to por causa do here?
The preposition de in por causa de must contract with the definite article of the noun that follows it. Since mofo (mold) is a masculine singular noun, it requires the article o. The preposition de and the article o contract into do.
