are constructions that are used in Japanese for expressing ‘something’, ‘anything’, or ‘nothing’. The main difference between the two being that 何（なに）も
is used with negative phrases (phrases that use ない
), while 何（なに）か
is used in other cases.
To use this expression, we simply need to put 何（なに）か
before the desired phrase.
Do you want to eat something?
There is nothing inside the refrigerator.
There are several casual forms of these expressions that are used in speech, or in certain dialects. These forms are なんにか, なんか, or なんにも, なんも.
