Is 何か an adverb?


> 何かいいことがあったか？
>
> 何か一言を言ってください

In sentences like these, is 何か an adverb? I have read that [counters such as
一つ are adverbs](https://en.wikibooks.org/wiki/Japanese/Grammar/Counters) when
used in sentences like りんごを一つ食べた. Is it possible that 何か is functioning like
an adverb similar to how 一つ is functioning like an adverb in that sentence.




何か can be used to mean 'something', which can also be an adverb; or
'anything', which can be used to describe the extent/magnitude, and is an
adverb in that case.

> 何かいいことがあったか？ - What's the good news? / Did something good happen?
>
> 何か一言を言ってください - Please say a few words.

How about

> りんごを一つ食べた, as opposed to 一つのりんごを食べた?

The former's 一つ functions as an adverb while the latter is just a noun.

So to answer your question: Yes, it is an adverb in those sentences.
