"Yes" pretty straightforward. はい, ええ, うん and そうです immediately come to mind. As for "No," I am afraid there are a lot of occasions where euphemism is preferred for fear of violating the politeness code or enraging the hearer.By the way, what Japanese words (common ones) are often used to say "yes" & "no" in conversation?
Hello Joannes,Thank you both!
I read IPA, if you care to give it a shot.
Yes: うん (un)Oh, I thought only "hai" and "iie" are formal, and "iya" and "ee" are informal.
So, what's informal for "yes/no" then?
