Prepositions

Latin sometimes uses prepositions, depending on the type of prepositional phrase being used. Most prepositions are followed by a noun in either the accusative or ablative case: "apud puerum" (with the boy), with "puerum" being the accusative form of "puer", boy, and "sine puero" (without the boy), "puero" being the ablative form of "puer". A few adpositions, however, govern a noun in the genitive (such as "gratia" and "tenus").
