Good evening everyone!

How can you say in russian: “ Родительного” is the genitive (case) of (the word) genitive?

What about: “Родительного – (это) родительный родительного”, from a grammatical point of view?
Or perhaps: “Генитива – (это) генитив генитива”?

From another point of view it’s a sort of self-referential statement which shouldn’t lead to any paradox (even in russian language...).
