Definition.—The Genitive showing in what a thing consists: hŏnōs cōnsŭlāatūs the office of-consul (lit. of-consulship).
Description.—Always with an Adjective accompanying: rēs māgni lăbōrĭs an affair of-great labour.
§ 144. The Genitive used Predicatively.—Most of the above Genitives can be used as the Predicate of a Noun: hortī sunt Caesăris the gardens are Cæsar's, rēs māgnī lăbōrĭs dūcĭtŭr the-affair is considered one of-great labour.
§ 145.—Genitive of the Object.—When a Genitive depends on a Noun which implies an action, it often denotes the object of the action, and corresponds to the Complement after a Verb § 115. Thus ămŏr ătrĭs the loce of-a-father may mean that someone loves a-father. This is called the "Objective" Genitive, ămŏr pătrĭs, may, however, also mean that a father loves someone, and the Gen. in this case corresponds to the Subject of a Verb. This is called the "Subjective" Genitive.
Subjective and Objective Genitives are often united: hostĭum tĭmŏr Caesărĭs the enemies' fear of Cæsar.
§ 146. Genitive with Verbs.—Certain Verbs, chiefly Transitive, take a Complement in the Genitive.
Genitive of the Charge.—Verbs of Accusing, Convicting, and Acquitting take a Genitive of the Charge: ambĭtūs accūsārĕ to-accuse of-bribery.
Genitive of the Mental Object.—Certain Verbs which denote pity, vexation, shame, disgust take a Genitive of the Object of the Feeling. These are mĭsĕrērī and the Impersonals of § 166 (b): mĭsĕrērĕ tŭōum pity your-friends, pŭdĕt mē frātrĭs I-am-ashamed of-my-brother.
Some Verbs of Remembering, Forgetting, etc., take a Genitive of the thing remembered, etc.; so admŏnērĕ to remind, certiōrem făcĕrĕ to inform: vīvōrum mĕmĭnī I-remember the living, certiōrem mē cōnsĭlī fēcĭt he informed me of his plan.
