secluded place; deep and quiet spot
A literary, somewhat poetic term for a remote, tranquil, and often mysterious location, far from human activity. Rare in everyday conversation.
The poet lived in seclusion in a deep, quiet place, away from the mundane world.
隠れ里 refers to a hidden village or community, often with a folkloric nuance. 幽邃境 is broader and can refer to any secluded natural spot, not necessarily inhabited.
Compound of 幽 (deep, dim, secluded), 邃 (deep, profound), and 境 (boundary, place). The exact historical derivation is uncertain; it is a literary coinage using classical Chinese-derived morphemes.
