also: まがりがわ
kanji radical 'curving river' (variant of radical 47)
Refers to the kanji radical 巛, a variant of radical 47 (川). This is a technical term used in kanji studies and dictionary contexts, not a word used in everyday language.
「巛」 is one of the kanji radicals, sometimes called 'magarikawa'.
The reading まがりかわ literally means 'curving river', describing the shape of the radical 巛. The alternate reading まがりがわ uses the voiced version of かわ. The kanji 巛 is a pictographic variant of 川.
