noun
crack; slit; crevice; crevasse
Rare literary term for a narrow opening or fissure, such as a crack in rock or a gap between objects. Not used in everyday conversation; 割れ目 or 隙間 are the common equivalents.
岩の罅隙から小さな花が咲いていた。
A small flower was blooming from a crack in the rock.
Compound of 罅 (ひび, crack) and 隙 (すき, gap). The exact historical derivation is uncertain; the spelling is conventionally associated with the meaning of a narrow fissure.
