# Totus — AP Latin Definition, Declension & Exam Guide

## Definition

Totus, tota, totum is the Latin adjective meaning "whole" or "entire." It declines like a first/second-declension adjective except in the singular genitive (totius) and dative (toti), making it one of the nine irregular adjectives you need to recognize on sight in Caesar and Vergil.

## What It Is

Totus, tota, totum means "whole," "entire," or "all of" something taken as one piece. So *totus exercitus* is "the whole army" viewed as a single unit, not "every soldier" individually.

What makes totus a key term instead of just vocabulary is its declension. It belongs to the famous group of nine irregular [adjectives](/ap-latin/key-terms/adjective "fv-autolink") (often remembered with the mnemonic UNUS NAUTA: unus, nullus, ullus, solus, neuter, alter, uter, totus, alius). These look like normal first/second-declension adjectives almost everywhere, but in the singular they take **-ius in the genitive** and **-i in the dative** for all three genders. That gives you *totius* (of the whole) and *toti* (to/for the whole). If you see *totius Galliae* and try to read *totius* as a nominative or some mystery [noun](/ap-latin/unit-3 "fv-autolink"), the sentence falls apart. Read it as a genitive and everything clicks: "of all Gaul."

## Why It Matters

[AP Latin](/ap-latin "fv-autolink") tests one core skill above everything else, which is reading Latin accurately, both in the required [Caesar](/ap-latin/key-terms/caesar "fv-autolink") and Vergil passages and at sight. Totus shows up constantly in both authors, and its irregular forms are a classic trap. *Totius* looks nothing like the genitives you drilled in first year, so the exam can quietly check whether you really know your forms by putting *totius* or *toti* in a sentence and asking what it modifies.

The most famous appearance is in the required Caesar syllabus. In *De Bello Gallico* Book 1, Orgetorix schemes to seize control *totius Galliae*, "of all of Gaul." If you misread that genitive, you misread his entire motive, and motive is exactly what short-answer and analysis questions ask about. Totus also matters for translation precision. The [literal translation](/ap-latin/unit-2 "fv-autolink") standard on FRQs rewards "the whole" or "entire," and knowing totus is an adjective agreeing with a noun (not a noun itself) keeps your translation grammatical.

## Connections

### [Adjective declension (Units 1-8)](/ap-latin/key-terms/adjective-declension)

Totus is the poster child for the nine UNUS NAUTA irregular adjectives. They all follow the same pattern, so once you can decline totus (totius, toti in the singular), you've also unlocked solus, unus, nullus, alter, and the rest. Learn one, get eight free.

### [Adjective agreement (Units 1-8)](/ap-latin/key-terms/adjective-agreement)

Totus has to match its noun in case, number, and gender, but Latin word order loves to separate them. In Vergil especially, totus can sit several words away from its noun, so the [ending](/ap-latin/unit-4 "fv-autolink") is your only clue. *Tota* + a feminine ablative noun three words later is still one phrase.

### [Ablative case (Units 1-8)](/ap-latin/key-terms/ablative-case)

Place-where phrases with totus often drop the preposition. *Tota urbe* means "in the whole city" with no *in* at all. If you're hunting for a preposition to explain an ablative and totus is in the phrase, that's probably your answer.

### Caesar, De Bello Gallico Book 1 (Unit 2)

Orgetorix's ambition for the *[imperium](/ap-latin/key-terms/imperium "fv-autolink") totius Galliae*, command "of all of Gaul," is one of the most-quoted phrases in the required Caesar reading. It's a ready-made example of the irregular genitive doing real interpretive work, since the whole conspiracy plot hangs on that phrase.

## On the AP Exam

On the multiple-choice section, totus shows up in syllabus passages and sight readings, and questions often hinge on identifying the case of *totius* or *toti* or naming which noun totus agrees with. On the free-response translation questions, the literal standard means you should render totus as "whole," "entire," or "all (of)," and you have to attach it to the right noun. A translation that turns *totius Galliae* into "all the Gauls" instead of "of all Gaul" loses the genitive and costs you the segment. No released FRQ tests totus in isolation, but it appears inside passages you're asked to translate and analyze, so treat it as a form you recognize instantly, not one you reconstruct under time pressure.

## totus vs omnis

Both translate as "all," but they slice the idea differently. Totus means "the whole of" one thing taken together (*tota urbs*, the entire city as a unit). Omnis means "every" or "all" of a group, item by item (*omnes urbes*, all the cities). They also decline differently. Omnis is a regular third-declension adjective, while totus is first/second declension with the irregular -ius/-i singular forms. Caesar uses both in Book 1, so the contrast is live in your required reading.

## Key Takeaways

- Totus, tota, totum means "whole" or "entire," describing one thing as a complete unit.
- It is one of the nine UNUS NAUTA irregular adjectives, taking genitive singular totius and dative singular toti for all genders.
- Everywhere outside the genitive and dative singular, totus declines like a normal first/second-declension adjective such as bonus.
- Phrases like tota urbe can mean "in the whole city" without a preposition, so don't panic when in is missing.
- Totus describes the whole of one thing, while omnis means "every" or "all" of many things.
- In the required Caesar reading, totius Galliae ("of all Gaul") names the prize Orgetorix and others scheme for, so misreading the form means misreading the plot.

## FAQs

### What does totus mean in Latin?

Totus, tota, totum means "whole," "entire," or "all of" something treated as a single unit. Totus exercitus is "the whole army," and totius Galliae is "of all Gaul."

### Is totus a regular first/second-declension adjective?

Mostly yes, with two big exceptions. The genitive singular is totius (not toti) and the dative singular is toti (not toto/totae) for all three genders. That pattern makes it one of the nine UNUS NAUTA irregular adjectives.

### What's the difference between totus and omnis?

Totus means the whole of one thing (tota urbs, the entire city), while omnis means "every" or "all" of a group (omnes urbes, all the cities). Omnis is also a regular third-declension adjective, while totus has the irregular -ius/-i singular forms.

### Why is the genitive of totus 'totius' and not 'toti'?

Totus belongs to a small group of nine pronominal adjectives (unus, nullus, ullus, solus, neuter, alter, uter, totus, alius) that borrow pronoun-style endings in the singular. All nine take -ius in the genitive and -i in the dative, regardless of [gender](/ap-latin/key-terms/gender "fv-autolink").

### Is English 'total' related to totus?

Yes. English words like total, totally, and totality come straight from Latin totus. That's a handy memory hook, since "total" and "the whole" mean basically the same thing.
