"prepositional case" 的定义和意义

What is the "prepositional case"?

The prepositional case is a grammatical case used to indicate the relationship of a noun or pronoun to a preposition, often expressing location or direction. It typically shows the idea of "in," "on," or "about" in relation to a noun. This case is found in languages such as Russian and Serbian, where it modifies nouns to reflect their role in relation to prepositions. For example, in Russian, the word for "book" is "книга" (kniga), and in the prepositional case, it becomes "книге" (knige), meaning "in the book." The prepositional case helps clarify the context of a noun within a sentence.
