甩shuǎi
to fling; to throw off
A modified form of 用 (yòng, to use) with the final stroke whipped outward - visually depicting the very action it names: a hand flicking something away. Treated as an ideographic whole, not analyzable into independent components. Indexed under Kangxi #101 用 (yòng) by tradition, since 甩 is essentially 用 with a flicked tail.
Filed under radical 用 (yòng, #101) by convention. 用 is not a separate component in 甩, so no strokes are highlighted.
