Thank you. That's really interesting. It makes me think of the character "names" in Genji Monogatari all being just titles or places where they live or whatever, and I think maybe I've read that even those were added later so the poor reader can cope more easily.Uh, the term "archaic" I mentioned above refers to almost "ancient," Heian Era, Nara Era, the era when the expression such like あれが初めてだったんだ never existed. 二重敬語(sometimes called 最高敬語) in archaic grammar, e.g. させ給ふ, おはします, was used to show who the subject/actor was without using a personal pronoun, because it was considered that to say directly an Imperial family's name was disrespectful.
So, is it an error by the author then? (plus, the dude's name is right there in the sentence, so that kind of defeats the purpose of the circumlocution anyway).
Suppose one did want to make おっしゃる passive, not for added respect but because one actually wants a passive sentence- is it possible?
(BTW, I apologize if I'm boring you guys now- it's not like there's anything particularly important about this one phrase- it's just how I learn; my poor brain doesn't know how to let go of things, lol).
