What does 嫌いなの (kirainano) mean


I know that kirai means to dislike or hate. And I know that nano can be used
as a question marker at the end of a sentence. But the context of where I saw
kirainano didn’t seem like it was a question. Is nano just a more casual way
of saying desu?




"なの" can be used as either a question marker or an explanatory marker
depending on intonation. Think of reading it as "嫌いなの？" versus "嫌いなの". In this
case, the context tells you that it means the latter.

嫌い is, sneakily, a な-adjective so the な must be linked to it and の itself is
an explanatory-の, which is described in more detail in this
[answer](https://japanese.stackexchange.com/a/5399/45675).

So, the speaker is explaining that they dislike the implied subject, which
would be a response to an inquiry such like:

> なぜそれを捨ててる **の** ですか？ **(Explain)** why are you throwing that away?
>
> 嫌いな **の** 。 **(Because)** I hate it.

Also, a super casual way of using です is to not use it at all. More formally
this sentence would be 嫌いなのです or 嫌いなんです.
