Questions & Answers about Nós vamos trabalhar juntos para salvar os animais.
Why do we need para before salvar?
In Portuguese, you use para followed by an infinitive verb (like salvar) to express purpose or intent, meaning "in order to." While English often just uses "to" (we work to save), Portuguese requires para salvar to clearly show the goal or purpose of the work.
Would juntos change if a group of women said this sentence?
Why use vamos trabalhar instead of the future tense trabalharemos?
You absolutely can use trabalharemos (we will work), but vamos trabalhar (we are going to work) is much more common in everyday spoken Portuguese. Just like in English, combining the present tense of ir (to go) with an infinitive is the most natural way to talk about future plans.
In English, we could just say "save animals" without "the." Why is there an os before animais?
Portuguese requires definite articles (o, a, os, as) much more often than English does. Even if you are talking about saving animals in a general, broad sense, you still need to include the article and say salvar os animais.
