Questions & Answers about Quando colaboramos, a comunicação é mais fácil.
Why doesn't this sentence use a reciprocal phrase like uns com os outros (with each other)?
I often see quando used with the future subjunctive. Why is colaboramos in the normal present tense here?
You use the future subjunctive with quando when you are talking about a specific hypothetical event in the future (like "When we collaborate next week..."). Because this sentence states a general, ongoing fact or habit ("Whenever we collaborate..."), it simply takes the present indicative.
The English translation says "communication", but the Portuguese sentence says a comunicação. Why do we need the article here?
In European Portuguese, definite articles (o, a, os, as) are required when talking about general or abstract concepts. While English drops the word "the" for abstract nouns like "communication", "life", or "time" in a general sense, Portuguese always includes the article.
