An adverbial genitive is a form of the genitive case used to express adverbial relationships, such as time, place, manner, or cause. It typically modifies a verb or an adjective, providing additional information about how, when, or where an action takes place. This usage is particularly common in certain languages, like Russian or Latin.

The genitive case is used to show possession or relationship between nouns in a sentence. It can also indicate the origin or material of something.
