In terms of declension, which case typically specifies the object of a verb?

The accusative case is typically associated with indicating the direct object of a verb in Latin. When a verb is used, it usually requires the action to be performed on something, and that something is represented by the noun in the accusative case. For example, in the sentence "Puella librum legit" (The girl reads a book), "librum" (book) is in the accusative case, showing that it is the object being acted upon by the subject "puella" (girl).

Other cases serve different grammatical functions: the nominative case identifies the subject of the verb, the vocative case is used for direct address, and the genitive case typically indicates possession or relationship. Thus, the accusative is the correct choice when discussing the grammatical role of specifying the object of a verb.
