なにか / なにも【か】

The question word なん何（なに）combines with the particles か and も to form indefinite expressions – "something" and "nothing/not anything."

なにか – something / anything

Adding か to なん何 creates なんか何か（なにか）, meaning "something" in statements or "anything" in questions.

When なんか何か is the object of a verb, the particle を is often omitted:

However, を can still be used for clarity or emphasis:

なんか何か can also appear before a noun to mean **"some kind of"** or **"some sort of"**:

なにも – nothing / not anything

Adding も to なん何 creates なん何も（なにも）, which is used with negative verbs to mean "nothing" or "not anything."

なん何も **always requires a negative verb**. Without the negative, the sentence is ungrammatical. The particle を is **not used** with なん何も, because も replaces it.
