noun
endlessness; eternity; without end
Abstract noun describing a state of having no end, often used in philosophical or poetic contexts. The reading むじゅう is obsolete.
宇宙の無終について考える。
I think about the endlessness of the universe.
この物語は無終の愛を描いている。
This story depicts an eternal love.
永遠 is the common word for 'eternity' and is used in everyday contexts. 無終 is more literary and emphasizes the absence of an end rather than infinite duration.
無限 means 'infinite' or 'limitless' and is more common than 無終. 無終 specifically focuses on the lack of an ending, while 無限 can refer to boundlessness in space, quantity, or possibility.
Compound of 無 (mu, 'without') and 終 (shū, 'end'). The reading むじゅう is an older voiced variant now considered obsolete.
