Teacher's Choice: Latin Prose

What this unit covers

All 46 terms we publish for Teacher's Choice: Latin Prose, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.

Gallia est omnis divisa in partes tres

The opening sentence. Ethnographic framing that presents conquest as description, and the first thing most Latin students ever read.

Caesar's third-person narration

Caesar writes "Caesar" rather than "I". Creates an appearance of objectivity for what is a political self-defense addressed to Rome.

Commentarii as a genre

Notionally raw material for historians rather than finished history. The plain style is a rhetorical choice that makes the account seem unshaped.

The Helvetii

The tribe whose migration opens the war. Caesar stops them at the Arar and Bibracte, presenting a war of choice as a defense of allies.

Orgetorix

The Helvetian noble whose conspiracy for kingship begins the narrative. His death conveniently precedes the migration Caesar then opposes.

Dumnorix and Diviciacus

Aeduan brothers, one hostile and one allied. Caesar spares Dumnorix at his brother's plea, demonstrating clementia while retaining leverage.

Ariovistus

The German king Caesar confronts in Book I. The parley and Caesar's speech justify extending the campaign beyond the Helvetii.

The bridge over the Rhine (Book IV)

Built in ten days and then destroyed. Caesar describes the engineering in detail because the point is Roman capability, not the brief crossing.

The first British expedition (Book IV)

A short, difficult landing with limited results. Caesar narrates the standard-bearer of the tenth legion leaping into the surf and shaming the men into following.

Caesar's ethnography of the Germans

Presented as harsher and less settled than the Gauls. The contrast justifies the Rhine as a natural frontier — a political conclusion offered as geography.

Roman military vocabulary: legio, cohors, centuria

A legion of about 4,800, ten cohorts to a legion, six centuries to a cohort. Needed to follow any battle narrative.

castra, castrorum (n. pl.)

A camp. Plural in form, singular in meaning; "castra ponere" is to pitch camp, "castra movere" to break camp.

impedimenta, -orum (n. pl.)

Baggage train. Its position in the column is repeatedly tactically decisive in Caesar.

obses, obsidis (m./f.)

Hostage. Caesar demands them constantly as a routine instrument of policy rather than as an exceptional measure.

frumentum, -i (n.) and res frumentaria

Grain and the grain supply. Logistics drive the campaigns more than battles do, and Caesar says so.

Indirect command (ut/ne + subjunctive)

After verbs of ordering, persuading or urging: "imperat ut veniant" — he orders them to come. Iubeo is the exception: it takes accusative and infinitive.

Fear clauses

timeo ne = I fear that something WILL happen; timeo ut = I fear that it will NOT. The reversal is counterintuitive and is regularly tested.

Ablative of comparison

After a comparative, ablative without quam: "Gallis fortiores" — braver than the Gauls. Equivalent to quam plus nominative.

Ablative of degree of difference

Answers "by how much": "multo maior" — greater by much; "paucis diebus post" — a few days later.

Accusative of extent and duration

Space traversed and time elapsed both go in the accusative without a preposition: "tres dies" — for three days; "milia passuum decem" — ten miles.

Locative case

For names of towns, small islands, plus domus, rus and humus: "Romae" at Rome, "domi" at home, "ruri" in the country.

Place constructions with towns

Names of towns take no preposition: "Romam" to Rome, "Roma" from Rome, "Romae" at Rome. Using ad or in with them is a standard error.

Partitive genitive

"pars militum" — part of the soldiers; "nihil novi" — nothing new. With numbers and quantities Latin often uses ex or de plus ablative instead.

The second British expedition (Book V)

Larger and better prepared than the first, reaching beyond the Thames, but again yielding tribute and hostages rather than occupation.

Cassivellaunus

The British leader who fights by ambush and chariot rather than pitched battle. Caesar's account of British chariot tactics is a valued ethnographic source.

The disaster of Sabinus and Cotta

A legion and a half destroyed after Ambiorix persuades them to leave camp. Caesar assigns the fault to Sabinus's decision, protecting the system while blaming the man.

Ambiorix

Leader of the Eburones and the most effective enemy in the work. His speech persuading the Romans to march out is a study in strategic deception.

Quintus Cicero at Nervian camp

Besieged and holding out until Caesar relieves him. The message smuggled in a spear-shaft is one of the most retold episodes.

Pullo and Vorenus

Two centurions whose rivalry drives them to rescue each other. Caesar uses them to illustrate virtus among ordinary officers rather than commanders.

The Gallic revolt of Book V

Ambiorix's success spreads rebellion across the north, showing Caesar's control was thinner than earlier books imply.

Druids (Book VI)

Caesar's account of their judicial authority, exemption from military service and taxation, and long oral training. A principal ancient source, and one written by an interested party.

Equites and plebs in Gaul

Caesar describes two classes that count and a mass that does not, mapped onto Roman categories — analysis and imposition at the same time.

Gallic religion in Roman terms

Caesar names Gallic gods as Mercury, Apollo, Mars, Jupiter and Minerva. Interpretatio Romana, useful evidence about Roman thinking as much as about Gaul.

The Hercynian forest

Caesar's account of vast German woods and their strange animals. Widely doubted as accurate, and valuable as evidence for how the Germans were imagined at Rome.

Caesar's clementia

Mercy toward the surrendered, contrasted with severity toward the treacherous — the Eburones are hunted. The pairing is presented as consistent policy rather than as inconsistency.

Why Caesar wrote the Commentarii

Published as the campaigns proceeded, they justified an extended command and kept his name before Rome. Reading them as neutral reporting misses their purpose.

Ablative absolute in Caesar

His signature construction for compressing sequence: "his rebus cognitis" — these things having been learned. It moves the narrative forward without a new main clause.

Perfect passive participle in narrative

Caesar chains them to compress events. English usually needs a finite clause: "obsidibus acceptis" becomes "after receiving hostages".

Relative clause of characteristic

qui + subjunctive describing a type: "sunt qui dicant" — there are those who say. Distinguished from an ordinary relative clause by the subjunctive.

Supine

Accusative in -um after verbs of motion for purpose ("legatos misit rogatum" — he sent envoys to ask); ablative in -u after adjectives ("mirabile dictu" — amazing to say).

Impersonal verbs

licet, oportet, necesse est, and the passive of intransitives: "pugnatum est" — there was fighting. Translating them literally produces nonsense.

Deponent and semi-deponent verbs

Deponents are passive in form and active in meaning — sequor, loquor, morior. Semi-deponents are deponent only in the perfect system — audeo, ausus sum.

Irregular verbs to know cold

sum, possum, eo, fero, volo, nolo, malo, fio. Their forms carry most of the sentences on the exam.

Translation scoring

Points are awarded for accuracy segment by segment: right vocabulary, right case and number, right tense and voice, right syntax. Elegant English that misses the syntax scores below literal English that gets it.

The short-answer questions

Answers must be in English and must cite the Latin. Referring to a line without quoting it, or quoting without translating the relevant words, loses the point.

The analytical essay

Requires evidence drawn from the required Latin AND from the English readings, cited specifically. A thesis without cited Latin cannot reach the top band.

What examiners penalize here

• The AP exam asks you to scan the first four feet of a designated Vergil line and often to identify the caesura. Practice marking elisions first — a missed elision throws off every foot after it. Write the macra and breves directly above the vowels to earn full credit.
• On the translation questions, always identify the **main verb** and its **nominative subject** first, then attach objects (accusative), possessors (genitive), and adverbial ideas (ablative). A quick case-map of the sentence prevents the most common mistranslations of who is doing what to whom.
• For the analytical essay, be ready to name a device (**simile, alliteration, hyperbaton, anaphora**) AND explain its effect with a Latin citation. Naming alone earns little; showing how, say, the Neptune simile links natural order to Roman civic authority is what scores.

Practice Latin

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
