The Perfect Pаssive System In the lаst mоdule, we lооked аt the forms of the passive in the present system of tenses: the present, the imperfect, and the future. In this quiz, we'll look at the perfect system of tenses: the perfect, the pluperfect, and the future perfect. With the completion of this work, we will have learned to form, identify, and translate all the forms of the present indicative verb in Latin! As we have seen, the present system of tenses in Latin, in both the active and the passive voice, is formed from the first two principal parts: for example, laudō, laudāre; audiō, audīre; and, agō, agere. When we learned the perfect active system of tenses we saw that these were formed on the basis of the third principal part, like laudāvī, audīvī, and ēgī. The perfect passive system, however, is formed from the fourth principal part, sometimes referred to as the supine: laudō laudāre laudāvī laudātum moneō monēre monuī monitum agō agere ēgī āctum audiō audīre audīvī audītum capiō capere cēpī captum dīcō dīcere dīxī dictum faciō facere fēcī factum The formation of the system of tenses is quite different to anything we've seen so far. The fourth principal part provides us with a participle in Latin, which works like an adjective; then, the person, number, tense, and mood of the passive verb is supplied by an auxiliary verb. We'll look at these details, and the formation of the verb itself, after some review!
