Definition & Meaning of "temporal case"

What is the "temporal case"?

The temporal case is a grammatical case used to indicate time-related relationships, often expressing the idea of "during," "at," or "in" regarding a specific time or period. This case helps clarify when an action occurs or how time relates to an event. The temporal case is found in languages such as Finnish and Estonian, where it modifies nouns to show temporal associations. For example, in Finnish, the word for "night" is "yö," and in the temporal case, it becomes "yössä," meaning "at night." The temporal case aids in providing context about the timing of actions in a sentence.
