THE FUTURE ACTIVE INFINITIVE 89 is declined and agrees with the word it modifies in gender, number, and case.

204. The perfect passive participle is declined like bonus, bona, bonum, and in the compound tenses (§ 202) it agrees as a predicate adjective with the subject of the verb.
 * 1. Inflect the perfect, pluperfect, and future perfect indicative passive of amō, moneō, regō, capiō, and audiō (§§ 488-492).

205. The perfect passive infinitive is formed by adding esse, the present infinitive of sum, to the perfect passive participle; as, am´t-us (-a, -um) esse, to have been loved; mo´nit-us (-a, -um) esse, to have been advised.


 * 1. Form the perfect passive infinitive of regō, capiō, audiō, and give the English meanings.

206. The future active infinitive is formed by adding esse, the present infinitive of sum, to the future active participle. This participle is made by adding -ūrus, -a, -um to the base of the participial stem. Thus the future active infinitive of amō is amat-ū´rus (-a, -um) esse, to be about to love.


 * a. Note that in forming the three tenses of the active infinitive we use all three conjugation stems:
 * Present, amāre (present stem), to love
 * Perfect, amāvisse (perfect stem), to have loved
 * Future, amātūrus esse (participial stem), to be about to love


 * 1. Give the three tenses of the active infinitive of laudō, moneō, regō, capiō, audiō, with the English meanings.
