middle fence; inner fence
Refers to a fence or wall that divides a space into inner and outer areas, often in traditional Japanese architecture or gardens.
庭の中垣の向こうに小さな池が見える。
A small pond can be seen beyond the middle fence in the garden.
Compound of 中 (naka, 'middle') and 垣 (kaki, 'fence'). The reading なかがき is a straightforward combination with rendaku voicing on the second element.
