na-adjective, noun
unspeakably wonderful; sublime; exquisite
Obsolete term for something so wonderful it is hard to describe. Not used in modern Japanese; the common word 微妙 (びみょう) has a different meaning.
古典文学では、「微妙」を「みみょう」と読んで、この上なく素晴らしい様子を表すことがある。
In classical literature, 微妙 read as みみょう can express an unspeakably wonderful state.
