Grammar · な-adjectives
好き and 嫌い, likes and dislikes
[Thing] が好きです / 嫌いです
Like and dislike are な-adjectives in Japanese, not verbs, and the thing liked takes が.
The mistake to avoid
を is wrong here. 寿司を好きです is one of the most recognisable beginner errors.
Examples
寿司が好きです。
すしが すきです。
I like sushi.
納豆が嫌いです。
なっとうが きらいです。
I don't like natto.
