42.1.40. 艮 (gen4, root)
Mnemonic: radical of roots (根 (gen1, roots))
Notes: this is a Kangxi radical, but its English name "stopping" is just too close to the more important "stop" 止 (zhi3, stop) and would cause confusion. So we just use the common phonetic compound roots (根 (gen1, roots)) as the mnemonic. It was tempting to leave "root" for 本 (ben3, potato), which looks perfectly like a root, but we did character first, and "potato" makes for even better mnemonics.
