Noun + が + 嫌い
Verb[plain, dictionary form] + の/こと + が + 嫌い
The structure ~が嫌いです is used to express disliking or having an aversion to something or someone. It attaches to nouns or verbs (converted to a nominal form with の or こと) to indicate what someone dislikes or finds unpleasant.
Note that です in this expression is the polite copula. It can be omitted in casual speech or conjugated (e.g., to the negative form).
Attach の or こと after the plain form of verbs to express that you dislike an action.
To express strong dislike, you can use 大嫌い (really hate):
For stronger emotions, you can also use とても (very) to intensify the dislike:
Negative Form: To say you do not "dislike" something (implying neutral or positive feelings), replace です with ではありません or じゃないです (or only じゃない in casual speech).
Question Form: Use 嫌いですか? (or 嫌い? in casual speech) to ask if someone dislikes something.
