Etymology

筋 combines 竹 (bamboo) and 肋 (rib), originally depicting the fibrous, sinewy structure of bamboo and the rib-like lines of the body, together conveying the idea of muscle and sinew.

Meaning mnemonic

Bamboo (竹) is full of strong fibers, and ribs (肋) are surrounded by muscle and sinew. Together they make 筋: the tough, stringy stuff that holds the body together and gives structure to a story.

Reading mnemonic

For キン, imagine a muscle-bound king flexing his sinewy arms: king -> キン, and his muscles are like taut fibers.
