Deponents Used Passively

A deponent such as hortor, hortārī, hortātus sum “encourage” normally uses passive-looking forms with active meaning: hortātur means “he encourages,” not “he is encouraged.” That principle is reliable, but it is not absolute. The gerundive of a transitive deponent is genuinely passive, some perfect participles acquire a passive or resultative reading, and a small number of lexemes admit exceptional passive uses.

This page is about those restricted uses. The default remains active: never translate a deponent passively merely because its ending looks passive. First identify the lexeme, then the particular non-finite form, and only then decide its voice from syntax and context. Unless labeled otherwise, the forms below belong to neutral Classical prose.

The default: passive form, active lexical voice

The visible endings of a deponent are the ordinary passive endings, but the dictionary entry tells you how the verb functions. Present hortor, hortāris, hortātur and perfect hortātus sum, hortāta est, hortātī sunt all have active meaning.

The final row is the crucial exception. Hortandus is not the perfect participle hortātus. It is the gerundive built on the present system, and its relationship to the noun is passive.

The first dux performs the encouragement and takes mīlitēs as its accusative object. The second dux receives the encouragement; mīlitibus is the dative of agent and names those on whom the obligation rests. English word order does not establish that contrast. Latin morphology and case do.

The gerundive keeps its passive force

The gerundive of a transitive deponent describes the person or thing to be affected by the action. Build it from the present stem, not from the English translation: hortā- gives hortandus; sequ- gives sequendus; imitā- gives imitandus. It declines like a first- and second-declension adjective and agrees with its patient.

With the impersonal gerundive construction, the action can be presented without a nominative patient. The person responsible is normally dative, not ā plus ablative.

Here proficīscor is intransitive, so neuter singular proficīscendum est is impersonal. Nōbīs marks the person under the obligation; it is not the receiver of an ordinary passive action. This distinction is developed on the gerundive of obligation page.

Perfect participles: active by rule, passive by lexical exception

The third and final principal part of a deponent normally supplies an active anterior participle. Thus secūtus means “having followed,” and hortātus means “having encouraged.” Agreement tells you which noun performed the deponent action.

Lūcia is feminine singular, so secūta agrees with her; amīcum is the accusative object of “having followed.” An English speaker who sees “was followed” in secūta est has read the participle’s surface morphology but ignored the lexical entry sequor.

Nevertheless, some deponent perfect participles can be understood passively or as resulting states when usage has licensed that interpretation. Comitātus, from comitor “accompany,” is the standard transparent example: depending on syntax, it can mean “having accompanied” or “accompanied.” This is a lexical exception, not a productive permission to make every deponent participle passive.

In the first sentence, sorōrem is an accusative object and Marcus performs the accompanying. In the second, the ablative phrase supplies the company surrounding the envoy, and comitātus is naturally resultative/passive. The repeated wording is deliberate: the construction, not the letters of the participle alone, determines the reading.

Finite passive readings are exceptional

Because the finite passive paradigm is already occupied by active deponent meanings, a transitive deponent generally cannot make a clear finite passive opposition. Classical Latin normally changes the construction or chooses a non-deponent synonym. For “the soldiers are encouraged by the commander,” dux mīlitēs hortātur may be recast with ordinary incitō: mīlitēs ā duce incitantur.

A few deponents show occasional finite passive senses in particular authors, and later Latin expands or reshapes some voice patterns. The standard lexical example is crīminor, which normally means “accuse” but can exceptionally mean “be accused.” Syntax, not the ending alone, must establish that reading:

Such uses are (literary), lexically restricted, or post-Classical—not a second paradigm that a B1 learner should produce freely. In ordinary Classical composition, use the gerundive where its meaning fits, use an ordinary passive synonym, or recast the sentence actively.

A parsing and production diagnostic

When reading a suspicious form, use this order:

1. Identify the dictionary verb. Is it actually deponent?
2. Name the form. A finite passive-form ending, a perfect participle, and a gerundive do not behave alike.
3. Find the participants. An accusative object supports an active reading; an agent phrase and nominative patient support a passive reading.
4. Apply the default. Finite and perfect forms of a deponent are active unless the lexeme and construction license something else; the gerundive is passive.
5. Translate last. English “was” plus a participle is an output, not evidence about the Latin analysis.

For production, begin from a Latin principal part. “Must be followed” leads to sequor, sequī, secūtus sum, then the present stem sequ- plus gerundive -endus: sequendus. It does not lead to a guessed form built from English “followed.”

Common Mistakes

1. Translating every passive-looking finite form passively

2. Giving a deponent perfect participle automatic passive force

3. Building the gerundive from the perfect participle

4. Inventing a regular finite passive for a deponent

Key Takeaways

The passive appearance of a deponent is not itself passive meaning. Finite forms and perfect participles are active by default; the gerundive is genuinely passive; a limited set of participles and rarer finite uses have lexically licensed passive readings. Parse the Latin form and its arguments before choosing an English voice.
