dislike; no liking for; no interest in
Used to express a lack of fondness or interest, often in contrast to 好き. Can sound slightly formal or emphatic compared to 嫌い.
彼は甘いものが不好きだ。
He has no liking for sweets.
私は人前で話すのが不好きです。
I have no interest in speaking in public.
Formed from the prefix 不 (ぶ, 'not') attached to 好き (すき, 'liking'). The reading ぶすき follows the on'yomi of 不 and the kun'yomi of 好き, a common pattern for negating native Japanese adjectives.
