noun
separation from the world; world-weariness; retirement from worldly affairs
Literary and rare; refers to a state of being detached from worldly concerns, often with a nuance of hardship or frustration leading to withdrawal. Found in classical Chinese-influenced texts.
彼は轗軻の思いを抱いて隠遁した。
He retired from the world with a feeling of world-weariness.
From Chinese 轗軻 (kǎnkē), originally meaning 'rough road' or 'hardship', later extended to 'frustration' and 'separation from the world'. The Japanese reading かんか is the on'yomi of the characters.
