Based on what Crystal responded above, can I please get some help understanding the usage of desu ga with this statement in lesson 2.3:
そう です か。へや を よやく したい の です が.
Sō desu ka. Heya o yoyaku shitai no desu ga. / I see. I'd like to book a room.
In the lesson, it was simply stated that it "shapes and softens a sentence" but from that explanation, I really don't understand how and when to apply it.
I'm also trying to understand the use of の in the same sentence. After doing some research, I understand its use to mean:
2) the thing is... here's the reason... (when explaining something)
3) generally expressing an explanation (I think?)
In the sentence above, is it being used because it's explaining that I'd like to book a room? Or does の mean something different when used in conjunction with です が?
