What is the conjugation of 「悲しきかな」?


Saw this in a blog post: 「悲しきかな読書への愛を育むほどに、夢は現実から遠ざかる」 It seems like 「悲しきかな」is
used as a na-adjective (形容動詞). Is this correct? I've never seen this form of
adjective before, what would its conjugation be?




No, it is not an independent adjective, but can be divided as 悲しき + かな, where
悲しき is a classical 連体形 (pre-noun form) and
[かな](https://dictionary.goo.ne.jp/word/%E3%81%8B%E3%81%AA/#jn-43372) is a
particle

> 体言・活用語の連体形に付いて、感動・詠嘆を表す。…だなあ。

> _Preceded by nouns or pre-noun form, indicates being impressed/exclamation.
> Translated as_ だなあ.

So a modern version would be 悲しいなあ, meaning _oh, how sad..._
