Definition & Meaning of "inessive case"in English

What is the "inessive case"?

The inessive case is a grammatical case used to indicate location within or inside something. It expresses the idea of "in" or "inside" in relation to a noun. This case is found in languages such as Finnish and Estonian, where it modifies nouns to show where something is situated.
