Morphemes in the word "что"

The word "что" in Russian consists of two morphemes: "ч" and "то".

The morpheme "ч" is a root morpheme, which carries the core meaning of the word. In this case, "ч" represents the interrogative pronoun "what" or "which".

The morpheme "то" is a suffix morpheme, which is added to the root to form a complete word. In this case, "то" is an emphatic particle that adds emphasis or importance to the word "ч".

So, in summary, the word "что" consists of the root morpheme "ч" and the suffix morpheme "то".
