recrimination, wrangling
辡 centers on mutual accusation and verbal conflict: two sides exchanging recriminations or engaging in wrangling.
辡 is composed of two 辛 (bitter, sharp) elements side by side, suggesting two parties exchanging sharp words. The exact historical development is uncertain, but the doubling of 辛 likely reinforces the idea of mutual accusation.
Two 辛 (bitter, sharp) components face each other like two people hurling bitter accusations back and forth. This visual doubling captures the idea of wrangling and recrimination.
For ヘン, imagine a hen clucking angrily back and forth with another hen: hen -> ヘン, and the two hens are wrangling just like the two 辛 sides.
