さく
裂く（さく）、分裂（ぶんれつ）、裂ける（さける）
to tear, split/division, to be torn
On-reading (レツ) is used in compounds; kun-reading (さ(く)) is used standalone or with okurigana. Appears in many compounds — memorize the key ones rather than the kanji in isolation. Has multiple meanings (tear; split; rend). Context determines which applies — pay attention in reading passages. This kanji forms verbs/adjectives with okurigana. Practice both the word form and compound forms.
