How does the hook in 甩 negative 用's meaning?
What's the correct term for this "hook"?


“乚” is named “cjk stroke swag” (u+31df), as used in “己”, the third stroke.

in chinese, it’s described as “豎曲鉤”, by the 教育部 異體字字典.

  The Cantonese reading is probably unrelated


such claiming is wrong. it’s a cantonese character (粵字)

in 廣東通志 卷五十一, page 30 mentioned:


  物之脫者曰甩・倫粒切・此粤字之隨俗撰出者也
