Mina-san!
In Lesson 3 for newbies (which I am), we got to:
O-genki desu ka?
Okagesama de, genki desu.
The latter translated "Thanks to you, I'm fine." I don't fully get that. '-sama' is used for ultimate respect, authority, like "Kami-sama" (God), right? So, I looked up "kage," and it means 'shadow.' So, O-kage-sama de, the way I figure this, would then mean something like 'Under the -sama/ueber shadow,' whch is to say, Under the protection of the heavens/gods, etc. So, what I don't understand is why "Hai, Okagesama de" means "Thanks to you."
Also, when people say, "Konnichiwa, ikaga desu ka?", what does 'ikagA' mean here? Something similar as OkagEsama de?
I hope someone is willing to clarify this for me.
Thank you.
