"grammatical case"の定義と意味

What is "grammatical case"?

Grammatical case is a linguistic category that indicates the function of a noun, pronoun, or adjective within a sentence. It shows the relationship between words and often reflects their role, such as the subject, object, or possessive form. Different languages have various cases, but common ones include nominative for the subject, accusative for the direct object, genitive for possession, and dative for the indirect object. For example, in English, the pronoun "I" is in the nominative case when used as a subject, while "me" is in the accusative case when used as an object. Understanding grammatical case is important for proper sentence structure and meaning, as it helps clarify the roles of words in a sentence.
