Disgust, Hate, Repugnance
noun, verbal noun, の adjective
You dislike someone so badly that it turns to disgust and hate.
けんお
This is a jukugo word that uses the on'yomi readings of the kanji. You haven't learned this reading for 悪 yet, so here's a mnemonic to help you: When you feel disgust for someone all you can manage to say when you see them is, "Oh... (お), it's you." Feel the anger when you see their face, "Oh, you again. Bleh."
彼女はいつも通り、私に嫌悪の目を向けてきた。
She looked at me with disgust, as usual.
ドラキュラはニンニクを嫌悪しています。
Dracula has an aversion to garlic.
もちろん嫌悪感を感じましたが、その時は何も言えませんでした。
Of course I felt disgusted, but I could not say anything at the time.
