noun
A sliding wooden bolt used to secure a door or window shut. This is a traditional architectural fitting, distinct from the pivot hinge sense. Cross-referenced with 猿 (sense 4).

Shortened reading; may appear in some dialects or older texts.
Variant reading; rarely used.
猿 (sense 4) refers to a similar sliding bolt or latch, often used interchangeably with 枢 in some contexts, but 猿 can also refer to a monkey or a specific type of wooden latch.
The kanji 枢 originally means 'pivot' or 'hinge' and is used in architectural contexts. The various readings (くるる, くろろ, くる, くるり) are native Japanese words for traditional door fittings, but their exact derivations are uncertain.
