Learn Portuguese (Portugal): É fundamental nós reunirmos o dinheiro para o transporte. - It is fundamental for us to gather the money for the transport.

Impersonal expressions like é fundamental can trigger either the subjunctive (when using que) or the personal infinitive (without que). This means É fundamental nós reunirmos is a direct alternative to É fundamental que nós reunamos. Many learners prefer this structure because the personal infinitive is often easier to conjugate than the subjunctive!

Since the ending of reunirmos already tells us it means 'we', do we have to include nós?

No, you can drop nós entirely and just say É fundamental reunirmos o dinheiro. Including the subject pronoun before a personal infinitive is just a common way to add a bit of emphasis or ensure absolute clarity about who needs to do the action.

Why do we use para instead of por when saying 'for the transport'?

We use para here because it shows purpose or destination. The money is specifically intended for the purpose of paying for transport. You would use por if you were talking about a direct exchange, a cause, or moving through a physical space.

Can the verb reunir be used for gathering both things and people?
