The perfect passive is an easy tense to form in Latin, and it is also one of the most useful. The verb "to love" in the perfect passive would translate into English as "I was loved".

Forming the Perfect Passive in Latin

In order to form the perfect passive you must be familiar with the principal parts of the verb with which you are working, e.g., amo, amāre, amāvī, amātum. The fourth principal part is the perfect passive participle.

• In its neuter nominative form, the perfect passive participle is identical to the nominative supine (a fourth-declension noun whose morphology and usage are very restricted). Be careful not to confuse the two.

To use the perfect passive, first determine the gender and number of the subject of the sentence. For example, in the sentence "The queen was killed by the soldier," queen is the subject. In Latin, queen will be feminine nominative singular (regīna).

Now make the participle agree with the subject in gender and number (and case), just as you would with any adjective. As a review, the singular endings for the participle, a first/second declension adjective, are:

  Masculine: -us — (amātus)
  Feminine: -a — (amāta)
  Neuter: -um — (amātum)

The endings for plural nouns are:

  Masculine: -ī — (amātī)
  Feminine:  -ae — (amātae)
  Neuter: -a — (amāta)

Now add a present form of sum, and you have the perfect passive.

Notes

1. Remember that the subject must agree with the passive participle.
2. Passive verbs do not take an object. Instead they have an agent or instrument, indicated by the ablative case.

Numquam enim ā Pomponiā nostrā certior sum factus esse cuī dare litterās possem. (Cicero, Ad Atticum 1.5)

"For I was never made aware by our Pomponia that there was someone to whom I could give a letter."
