은가

I wonder whether it's...

Wonders about a quality, often as an unspoken worry: do they dislike me, is the material too thick, does that sound too crude, is that actually good nutrition. It can also pose a rhetorical challenge, as in the line asking whether you aren't behaving like a spoiled child yourself. Followed by 보다 it means 'seems' or 'apparently' — you think this'll make you the nation's MC or something. Adding 요 turns it into a polite question.
