nari-adjective (archaic / formal)
quiet; calm; leisurely; composed
Archaic adjective describing a serene, unhurried state of mind or atmosphere. In modern Japanese, this meaning is usually expressed by words like 静か or 落ち着いた.
古典では「悠なる心」のように使われる。
In classical texts, it is used like 'a calm heart'.
The expression 'distant sky' appears in old poetry.
遠い is the plain modern word for physical or temporal distance, while 悠 evokes a vast, boundless distance in archaic or poetic style.
落ち着いた is the common modern way to describe a composed manner, whereas 悠 conveys the same composure but only in old or literary usage.
果てしない is the standard modern adjective for 'endless', matching the boundless-in-time-or-space sense that 悠 expresses archaically.
