Almost always appears with the particle に: 粉々(こなごな)()れる (to shatter into pieces), 粉々(こなごな)(くだ)く (to crush to bits), 粉々(こなごな)になる (to be smashed to pieces). Can also function as a na-adjective: 粉々(こなごな)状態(じょうたい) (a shattered state). The word is a reduplication of (こな) (powder), emphasizing complete fragmentation. Related: ばらばら (scattered in pieces — suggests separation rather than shattering), めちゃくちゃ (wrecked, in a mess — broader destruction).
