NUMBER AND CASE[*] 35. Nouns, Pronouns, Adjectives, and Participles are declined in two Numbers, singular and plural; and in six Cases, nominative, genitive, dative, accusative, ablative, vocative. [*] a. The Nominative is the case of the Subject of a sentence. [*] b. The Genitive may generally be translated by the English Possessive, or by the Objective with the preposition of. [*] c. The Dative is the case of the Indirect Object (§ 274). It may usually be translated by the Objective with the preposition to or for. [*] d. The Accusative is the case of the Direct Object of a verb (§ 274). It is used also with many of the prepositions. [*] e. The Ablative may usually be translated by the Objective with from, by, with, in, or at. It is often used with prepositions. [*] f. The Vocative is the case of Direct Address. [*] g. All the cases, except the nominative and vocative, are used as objectcases; and are sometimes called Oblique Cases ( cāsūs oblīquī ). [*] h. In names of towns and a few other words appear traces of another case (the Locative), denoting the place where: as, Rōmae, at Rome; rūrī, in the country.
[*] Note.--Still another case, the Instrumental, appears in a few adverbs (§ 215. 4).
