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