How to say “grammatical case” in Chinese? How do you call “grammatical case” in Chinese? I mean the property of grammar where nouns change based on their function in sentence, for instance like in Russian or to lesser extent in German.

I have found 语义格 and 格语法, the second one seems better. Are there better ways to say that?

Also: how to say “case ending”?
It is just 格, while the Wikipedia page also lists 语义格 as a possibility.

格语法 is not acceptable, as it would mean a grammar of some kind, but not "case".

"case ending" might be 格词尾.
