〜わけではない

嫌(きら)いなわけではありません。

Kirai na wake de wa arimasen.

It is not that I dislike it.

A partial denial — it corrects a misreading rather than denying outright

お金(かね)がないわけではないが、使(つか)いたくない。

Okane ga nai wake de wa nai ga, tsukaitakunai.

It is not that I have no money; I just do not want to spend it.

It often pairs with a turn, denying one reading before giving the real reason

全部(ぜんぶ)が悪(わる)いわけではありません。

Zenbu ga warui wake de wa arimasen.

It is not that all of it is bad.

With 全部, みんな or いつも it denies the whole rather than the thing
