1. Essentials at a Glance

The Double Accusative in Latin grammar occurs when a single verb governs two objects in the accusative case. It most commonly appears with verbs of teaching, asking, making, calling, or similar “factitive” verbs. One accusative is typically a person or primary object; the other is a complement or thing. Mastering this usage refines your understanding of Latin syntax and offers crucial insight into accurate translation and nuanced reading comprehension.

2. Definition & Importance

A Double Accusative arises when a Latin verb takes two accusative objects simultaneously. Common verbs include docēre (“teach”), rogāre (“ask”), and facere (“make” or “appoint”). This construction is central to Latin sentence structure since it highlights how certain verbs can express both a person and a thing or complement without resorting to an indirect object. Mastering the Double Accusative in Latin grammar improves reading fluency, clarifies clause relationships, and helps avoid common errors in double accusative usage.

3. Forms & Morphology

Below is a brief table illustrating common endings for the double accusative in the singular forms of the first two declensions. Note that both objects simply appear in the standard accusative case:

• No special or unique accusative ending exists just for the double accusative.
• Each accusative noun (or pronoun) declines according to its own declension and gender.
• Predicative adjectives or nouns (e.g. mē hērēdem fēcit) also agree in case (accusative) with the object they describe.

4. Usage & Examples

1. Tē litterās doceō
   I teach you letters.

   • docēre can govern both “you” (the person taught) and “letters” (the content).

2. Mē hērēdem fēcit
   He made me heir.

   • The verb fēcit takes two accusatives: mē (the person changed) and hērēdem (the new status).

3. Tē sententiam rogō
   I ask you (for) your opinion.

   • rogāre commonly takes the person and the thing asked for, both in the accusative.

4. Urbem Rōmam vocāvit
   He called the city Rome.

   • One accusative is urbem (the entity named), the other is Rōmam (the new name).

5. Nōn tē cēlāvī sermōnem
   I did not hide the conversation from you.

   • cēlāre can take both a person (the one left uninformed) and a thing (the concealed fact).

5. Common Pitfalls

• Forgetting which verbs allow the double accusative (e.g., docēre, rogāre, vocāre, facere); many other verbs require prepositions or different cases.
• Mixing up dative vs. accusative: some verbs (e.g., dō, dīcō) take a dative for the person instead.
• Confusion in passive voice: one accusative may “remain” in the accusative as a retained object, so identify carefully which accusative becomes the subject.

6. Additional Notes & Nuances

In passive transformations, Latin can make either the person or the thing the subject. For example, tū litterās docēris (“you are taught letters”) keeps litterās in the accusative. Poetic texts sometimes stretch these rules, such as using lateō with an accusative of person. Historian prose (e.g., Cicero, Livy) often employs a retained accusative in passive clauses, showing the construction’s versatility across genres.

7. Key Takeaways

• Memorize key verbs (e.g., docēre, rogāre, facere, vocāre) that typically accept two accusatives.
• Context determines roles: one accusative often identifies a person, the other an object or predicate.
• Check passive clauses: either object can become the subject, and the other may remain accusative.
• Avoid confusion with indirect objects: many verbs require dative or a preposition instead of a second accusative.
