解決（かいけつ）、解く（とく）、理解（りかい）、解説（かいせつ）

solution, to solve, understanding, explanation

On-reading (カイ) is used in compounds; kun-reading (と(く)) is used standalone or with okurigana. Appears in many compounds — memorize the key ones rather than the kanji in isolation. Has multiple meanings (solve; untie; explain). Context determines which applies — pay attention in reading passages. This kanji forms verbs/adjectives with okurigana. Practice both the word form and compound forms.
