noun
empty grain husk; hollow object
Primarily refers to empty husks of grains like rice or wheat; also used for any hollow or empty object. Often appears in agricultural or botanical contexts.
この稲穂には粃が多くて、収穫が少ない。
This rice ear has many empty husks, so the harvest is small.
風で粃が飛ばされて、実だけが残った。
The empty husks were blown away by the wind, leaving only the grains.
noun
unripe fruit
Refers to fruit that has not ripened; less common than the husk sense. Often used in agricultural or botanical descriptions.
まだ粃の柿は渋くて食べられない。
The unripe persimmons are still astringent and cannot be eaten.
Variant kanji form; less common than 粃.
The origin is uncertain. The kanji 粃 and 秕 both contain the rice radical 米, indicating association with grains. The reading しいな is native Japanese, and the variant readings しいだ and しいら are obsolete.
