Superessive case
The Superessive case is a grammatical declension indicating location on top of something. (Its name comes from Latin supersum, superesse: to be over and above.)
While most languages communicate this concept through the use of prepositions, there are some (most notably the family of Finno-Ugric_languages which includes Finnish and Hungarian) which make use of cases for this grammatical structure.
An example in Hungarian: a könyveken means ?on the books?, literally ?the books (on)?
