A person who withdraws from society to live in solitude, often with a nuance of deliberate seclusion.
He left the city and lives as a recluse deep in the mountains.
Compound of 隠遁 (いんとん, 'seclusion') and 者 (しゃ, 'person'). The exact historical derivation is uncertain, but the spelling is conventionally associated with the meaning of a person who lives in seclusion.
