Mnemonic

grandma sits winding silk onto a spool, pulling and twisting fibers in endless loops. A flock of birds spirals outside her window in the same repetitive circular pattern, mimicking grandma's reeling motion. Round and round, the birds and her winding never stop.
Additional thoughts
Picture grandma's hands turning the spool while birds outside trace identical spirals in the sky—both locked in the same hypnotic, repetitive loop. The shared circular motion ties the radicals together.
Quick recall
grandma reels silk while a flock of birds spirals overhead, both caught in endless winding loops.

Details

The keyword for 繰 is winding. This kanji refers to the act of reeling, spinning, or winding thread or yarn, as in drawing out silk fibers from cocoons and twisting them together. By extension, it also conveys the idea of repeating an action over and over, much like the repetitive circular motion involved in winding thread onto a spool. It captures both the physical process of handling fibers and the broader sense of doing something again and again.
