嫌悪 (けんお) uses the On'yomi for both kanji. 嫌 (ken) means "dislike" or "detest," and 悪 (o) means "bad" or "evil." "きらい" is the Kun'yomi for 嫌, incorrect for this compound. Misreading 嫌 as げん is also incorrect. It signifies strong "disgust, hatred, or aversion," a profound negative emotional response.

嫌悪（けんお）は、両漢字が音読みです。「嫌」は「嫌う」、「悪」は「憎む、悪い」を意味し、「ひどく嫌い憎むこと」を指します。誤読の「げんお」は「嫌」の読み間違いで、「きらい」は訓読みです。強い不快感や憎悪を伴う感情を表します。
