Perfect Passive Indicative

The Latin perfect passive indicative combines an agreeing perfect passive participle with the present indicative of sum: laudātus est “he was praised / has been praised,” laudāta est “she was praised,” and laudāta sunt “the neuter things were praised.” It presents the reception of an action as a completed fact.

This is a two-word finite verb phrase, but its tense is perfect, not present. The participle supplies completed passive meaning; sum, es, est, sumus, estis, sunt supplies person and number. The participle also agrees with the subject in gender, number, and nominative case. Unless noted otherwise, these forms belong to neutral Classical prose.

Build the participle from the fourth principal part

The active perfect system uses the third principal part; the passive perfect system uses the perfect passive participle associated with the fourth. A dictionary often cites that fourth part as a supine in -um, from which the participial stem is apparent:

The two principal-part families must not be blended. Scrīpsit is active “he wrote”; liber scrīptus est is masculine singular passive “the book was written.” The change from scrīps- to scrīpt- is lexical information supplied by the principal parts.

The complete paradigm

With a masculine subject such as discipulus:

If the speaker is female, “I was praised” is laudāta sum. A group of women says laudātae sumus. A neuter plural subject takes laudāta sunt. Person comes from sum; gender and number agreement come from the participle.

One perfect, two common English renderings

Like the active perfect, the passive perfect can narrate a bounded past event or emphasize a result relevant now:

Latin morphology is perfect passive in both sentences. Herī makes English simple past natural in the first; the present consequence favors English present perfect in the second. Do not treat “was” and “has been” as two separate Latin tenses here.

Caesar begins Dē bellō Gallicō 1.1 with a resultative perfect passive (literary, geographical prose). The quotation is reproduced without added macrons:

Although idiomatic English describes the resulting state with “is divided,” dīvīsa est has perfect-passive form. The feminine singular participle agrees with Gallia.

The construction can also be resultative, and context may allow the English state “is closed.” Yet Latin still contains a perfect passive participle plus est. Distinguish grammatical analysis from the smoothest translation.

Perfect passive versus present and imperfect passive

Latin's synthetic present-system passives use personal endings on one word. Compare:

English “was praised” can correspond to either imperfect laudābātur or perfect laudātus est. Ask whether the Latin presents an ongoing background process or a complete event.

Agent, means, and word order

A personal agent normally takes ā/ab plus the ablative: ā magistrō “by the teacher,” ab amīcīs “by friends.” An instrument or means normally uses the bare ablative: gladiō vulnerātus est “he was wounded with a sword.” This difference is explained further under the ablative of agent.

Here ā latrōne names the person acting, while gladiō names the instrument. English uses “by” and “with”; Latin case structure carries the distinction.

The participle and sum need not stand next to each other. Latin word order may place the subject, agent, or other material between them, especially for emphasis (literary or elevated prose when strongly separated). Agreement and the finite form of sum keep the construction identifiable.

Special lexical cautions

Not every verb has an ordinary personal perfect passive. Intransitive verbs generally cannot be passivized personally because they have no direct object to become the subject, though Latin can use an impersonal neuter singular: pugnātum est “there was fighting / a battle was fought.” Deponent verbs use passive-looking perfect forms with active meaning: profectus est means “he set out,” not “he was set out.” These are lexical facts and must be learned from the dictionary entry.

Do not manufacture a passive merely because English permits one. First confirm that the Latin verb is transitive and has an attested perfect passive participle.

Classical authors also sometimes use perfect fuī in place of present sum: laudātus fuī can function as a perfect passive alongside regular laudātus sum. The fuī series may bring the completed event or the end of a resulting state into sharper focus, but the contrast is not a rigid second paradigm with a different English tense. For secure production, use the regular sum series and recognize the fuī series in reading.

Common Mistakes

1. Using the active perfect stem in a passive phrase. The passive uses the participial family.

2. Failing to make the participle agree with the subject. English participles do not show this agreement; Latin ones do.

3. Treating est as proof of present tense. The participle changes the tense of the whole verbal phrase.

4. Adding ā/ab before an instrument. Reserve it for a personal agent in the ordinary construction.

5. Reading a deponent perfect as passive. Dictionary voice determines the meaning.

Key Takeaways

Form the perfect passive indicative with a perfect passive participle from the fourth-principal-part family plus present sum. Make the participle agree with the subject in gender and number, and let sum mark person and number. Interpret the completed passive event as “was praised” or “has been praised” according to context. Keep it distinct from synthetic present and imperfect passives, from the third-principal-part active perfect, and from passive-looking deponent forms with active meaning.
