I came across a long sentence in a story, which I have googled around and struggled for a couple of days. Here is what it reads:
My rough translation would be:
At this time, you come to understand a fact that, in among the travelers, for the sake of precaution, they only return our greetings so much with a nod, and quite a few simply do not return greetings at all.
I’m not sure if I have got the idea right. But what haunting me most is the “が” in the first phrase この頃わかってきたのだが. What is “が” doing here for? There is no contradictory sense in the sentence. I mean, there is no need for “が” to function as a button to remind the readers that something contradictory is coming up.
Besides, I discovered that in some subjunctive sentences, they put a “が” at the end too, such as:
(If I were a bird, I would fly to you.)
There you go, “が” is haunting again.
Please enlighten me. Thank you.
