Определение и Значение "genitive case"

What is the "genitive case"?

The genitive case is a grammatical case used to show possession or relationship between nouns. It indicates that one noun belongs to or is associated with another noun. The genitive case often translates to "of" or uses an apostrophe and "s" in English. This case is found in various languages, such as Latin and German, where it modifies the form of nouns to express ownership. For example, in Latin, the word for "book" changes from "liber" to "libri" to indicate "of the book." The genitive case helps clarify relationships between different elements in a sentence.
