"adessive case"の定義と意味

What is the "adessive case"?

The adessive case is a grammatical case used to indicate location on or at something, as well as possession or the means by which something is done. It often translates to "on," "at," or "by" in English. This case is found in languages such as Finnish and Estonian, where it changes the form of nouns to express location or instrumentality. For example, in Finnish, the word for "table" is "pöytä," and in the adessive case, it becomes "pöydällä," meaning "on the table." The adessive case helps clarify where something occurs or how an action is carried out.
