Turba, turbae (f.) is a first-declension Latin noun on the AP required vocabulary list meaning crowd, throng, or commotion. It's polysemous, so context decides whether Vergil means a mob of people or general chaos, and it shares a root with turbo (whirlwind) and turbare (to disturb).
Turba, turbae is a feminine first-declension noun that means crowd, throng, mob, or, more abstractly, disturbance and commotion. The two meanings are really one idea. A turba is a mass of people (or things) in disordered motion, which is why Latin uses the same root for whirlwinds (turbo, turbinis) and the verb turbare, "to stir up, throw into confusion." When you see any turb- word, think "chaotic swirl."
On the AP exam, turba is exactly the kind of polysemous word the CED warns you about. In Aeneid 6, the turba rushing to the banks of the Styx is a literal crowd of souls. In a storm or battle scene, turb- words lean toward turmoil and disorder. Your job is to read the context, check the case ending (turba nominative subject vs. turbā ablative "in/with a crowd"), and pick the meaning that fits the sentence, not just the first gloss you memorized.
Turba lives in Unit 1 (Suggested Practice – Latin Prose) and maps to Topic 1.20, the storm and divine intervention scene in the Aeneid. It hits all three of that topic's learning objectives. For AP Latin 1.20.A, it's a required vocabulary word you simply have to know. For AP Latin 1.20.B, it's a textbook polysemous word, since "crowd" and "uproar" are both live options until context settles it, and its word family (turbo, turbare, turbidus) is a perfect example of using roots to decode unfamiliar vocabulary. For AP Latin 1.20.C, its case does real work: turba as nominative is the actor (the crowd rushes), while ablative turbā often sets the scene (amid the throng). Thematically, turba is Vergil's shorthand for the disorder that gods like Aeolus unleash and figures of authority calm, which is the whole engine of the storm episode.

Aeolus (Unit 1)
Aeolus keeps the winds locked up precisely because, once released, they become a turba in the abstract sense, a swirling chaos that wrecks the Trojan fleet. The storm scene is turba written across the sky and sea.
Fama (Unit 1)
Fama, the personified Rumor, feeds on crowds. She spreads fastest through a turba, so the two concepts pair naturally when Vergil shows how panic and gossip move through masses of people.
Trojans (Unit 1)
The Trojan refugees are themselves a displaced multitude, and Vergil often frames them against a hostile or chaotic turba. Order versus crowd-chaos is one of the epic's running contrasts, capped by the statesman simile in Book 1 where one authoritative man calms a riotous mob.
Fatum (Unit 1)
Fatum is the fixed, ordered plan of destiny; turba is its opposite, disorder and commotion. Vergil's plot is basically fate imposing order on turba, scene after scene.
Turba shows up most directly on translation questions. The 2023 Translation FRQ (Q1) was the Sibyl describing the Styx to Aeneas, the passage where a whole turba of souls pours toward the riverbanks. Translating it as "crowd" or "throng" there earns credit; translating it as vague "trouble" would miss the literal sense. On multiple choice, expect questions that test the word's meaning in context (per 1.20.B) or ask you to identify its case and function (per 1.20.C), since turba/turbā only differ by vowel length. On analytical essays, turb- vocabulary is great evidence when you're arguing about chaos, divine disruption, or mob behavior, because you can point to the word itself doing the work.
Turba (1st declension, feminine) is a crowd or commotion. Turbo (3rd declension, masculine) is a whirlwind or spinning thing, like the turbine the winds use to blast the land in Aeneid 1. They share a root but decline completely differently, so a form like turbine can never come from turba. If you see turbine and translate "crowd," you've grabbed the wrong noun.
Turba, turbae (f.) is a first-declension noun on the AP required vocabulary list meaning crowd, throng, or commotion.
It's polysemous, so context decides whether it means a literal mass of people or abstract turmoil and disorder.
Its word family (turbo, turbare, turbidus) all share the idea of chaotic swirling, which helps you decode unfamiliar turb- words per LO 1.20.B.
The 2023 Translation FRQ featured turba describing the souls crowding the banks of the Styx in Aeneid 6.
Don't confuse turba with turbo, turbinis (whirlwind), a separate third-declension noun with totally different forms.
Case matters because nominative turba is the subject doing the rushing, while ablative turbā usually means 'in' or 'amid the crowd.'
Turba, turbae is a first-declension feminine noun meaning crowd, throng, or mob, and by extension commotion, disorder, or uproar. It's on the AP Latin required vocabulary list.
No. Turba can mean a literal crowd, like the souls at the Styx in Aeneid 6, or abstract turmoil and confusion. Context clues tell you which sense Vergil intends, which is exactly what learning objective 1.20.B tests.
Turba (1st declension, feminine) is a crowd or commotion; turbo, turbinis (3rd declension, masculine) is a whirlwind. Forms like turbine come from turbo, not turba, so check the declension before you translate.
Yes. The 2023 Translation FRQ (Q1) drew from the Sibyl's description of the Styx in Aeneid 6, where a turba of souls rushes to the riverbanks, and translating it accurately as 'crowd' or 'throng' was part of earning full credit.
First declension endings do the work. Turba is nominative singular (the crowd acts), turbam is accusative (the crowd receives the action), and turbā with a long a is ablative, often meaning 'in' or 'with the crowd.' Identifying that function is what LO 1.20.C is asking for.
