Why is this sentence like this なんと ～であることか and not like なんと ～でしょう?


> **なんと** 醜い私の声 **であることか。**

I wanted to know the difference. Is it the nuance?

Could someone explain it to me?

Thanks in advance! :]




Simply なんと～(こと)でしょう is politer because でしょう is the polite form of だろう. It
would be used when the speaker is talking politely, i.e., using ～です/～ます. Folk
tales for children are usually narrated in this tone.

なんと～(こと)だろう is the non-polite equivalent, which is typically found in modern
novels targeted at adults.

なんと～(こと)か is roughly the same as なんと～(こと)だろう, but it sounds a bit more
literary and stiff. I don't think it's archaic. [More examples
