解く vs. 説く (Toku): To Solve/Untie vs. To Explain in Japanese
Both 解く and 説く are pronounced toku (とく). Learn how Sword+Cow+Horn (解) means Solve/Untie while Speech+Older Brother (説) means Explain.
In Japanese, 解く (とく) and 説く (とく) share the exact same Kun'yomi reading toku. Even more interestingly, in English both relate to making something clear — yet 解く means to untie a knot or solve a math/test problem, whereas 説く means to explain a theory or persuade someone with words.

解 (かい / とく) is built from three vivid pieces: a Horn/Corner (角) on the left, a Sword (刀) at the top-right, and a Cow (牛) at the bottom-right — using a blade to separate the horn from the cow, literally taking apart / untying / solving a knot or puzzle! 説 (せつ / とく) has the Speech radical (言) on the left and Older Brother (兄) with antenna horns on the right — an older brother using spoken words to explain a concept (as in 説明 explanation).
