戒める（いましめる）、戒め（いましめ）、警戒（けいかい）

to warn, warning, vigilance

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