Definition & Meaning of "superessive case"

What is the "superessive case"?

The superessive case is a grammatical case used to indicate a location on or at a surface. It expresses the idea of "on" or "at" in relation to a place or object. This case is found in languages such as Hungarian and Estonian, where it modifies nouns to show where something is situated. For example, in Hungarian, the word for "table" is "asztal," and in the superessive case, it becomes "asztalon," meaning "on the table." The superessive case helps clarify the position of an object or subject in relation to a surface in a sentence.
