KanjiJLPT N1
Chafe

chafe, rub, polish, grind, scrape

Mnemonic

You grab a coil of hemp rope with your bare hand and start hauling it in. The rough, coarse fibers drag across your palm, and the friction begins to chafe your skin raw—blistering red lines forming where the hemp keeps grinding against your hand with every pull.
Additional thoughts
Picture the texture of hemp rope vividly—those scratchy fibers sawing back and forth across soft skin. The hand gripping tighter only makes the chafing worse, a painful cycle of friction.
Quick recall
Pulling hemp rope with your bare hand chafes your skin raw.
