Finnish, among a few other languages, is known for its partitive case. I have been told that in some Germanic language, partitive case is required whenever SV-order is absent. SV-order is absent, e.g., in the following English example:
There are cows in the barn.
Since the subject cows follows the verb are, SV-order is absent.
During a recent discussion of this kind of existential construction in English, someone mentioned to me that in some Germanic languages semantic subjects following the verb would be marked by the partitive. To my chagrin, I failed to follow up on this matter. I have never encountered anything like partitive case in Germanic languages, even though I learned five of them.
Does anybody know whether there is a Germanic language with partitive case? If yes, is the partitive case then used for semantic subjects that follow the verb?
