# Agreement — AP Latin Definition & Translation Guide

## Definition

In AP Latin, agreement is the grammatical rule that adjectives, pronouns, and participles must match the noun they modify in case, number, and gender (CED 6.4.A), which lets you pair words correctly even when Latin word order scatters them across a line of poetry.

## What It Is

Agreement is the matching system that holds a Latin sentence together. An [adjective](/ap-latin/key-terms/adjective "fv-autolink") or pronoun must share three things with the [noun](/ap-latin/unit-3 "fv-autolink") it modifies: **case** (its job in the sentence), **number** (singular or plural), and **gender** (masculine, feminine, or neuter). The CED states this directly in the essential knowledge for 6.4.A: "Adjectives must agree with the nouns they modify in case, number, and gender."

Here's why this matters more in Latin than in English. English uses [word order](/ap-latin/key-terms/word-order "fv-autolink") to show what goes with what. Latin doesn't have to. A poet like Ovid can put an adjective at the start of a line and its noun at the end, and agreement is the only thread connecting them. When you see *puellae* and need to know whether *pulchrae* describes it, you check the endings. If the case, number, and gender all line up, they're a pair. Agreement is basically the GPS of Latin poetry, and without it you're guessing.

## Why It Matters

Agreement lives in Topic 6.4 (Ovid, *Amores* 1.9 and 3.1) under learning objective [AP Latin](/ap-latin "fv-autolink") 6.4.A, which asks you to describe how adjectives and pronouns function in context and contribute to meaning. But it's not just a [Unit 6](/ap-latin/unit-6 "fv-autolink") skill. Every translation passage on the AP Latin exam, Vergil or Caesar, prose or poetry, depends on you tracking agreement correctly. In elegy especially (the love-poetry genre from 6.4.B), Ovid separates adjectives from their nouns on purpose. That word placement creates suspense, emphasis, and word pictures, and the exam expects you to untangle it. Misreading one agreement pair can flip the meaning of a whole couplet, and the literal-translation scoring on FRQs punishes exactly that kind of mistake.

## Connections

### [Participle (Unit 6)](/ap-latin/key-terms/participle)

Participles are [verbal](/ap-latin/unit-5 "fv-autolink") adjectives, so they follow the exact same agreement rule. A participle like *amans* or *captus* must match its noun in case, number, and gender, which is how you figure out who is doing or receiving the action.

### [Ablative Absolute (Unit 6)](/ap-latin/key-terms/ablative-absolute)

The [ablative absolute](/ap-latin/key-terms/ablative-absolute "fv-autolink") is agreement in action. You spot one by finding a noun and a participle that both sit in the ablative and agree with each other, like *urbe capta* ('with the city having been captured').

### [Relative Clauses (Unit 6)](/ap-latin/key-terms/relative-clauses)

Relative [pronouns](/ap-latin/key-terms/pronoun "fv-autolink") follow a half-agreement rule that the exam loves to test. The pronoun (*qui, quae, quod*) takes its number and gender from its antecedent, but its case comes from its job inside its own clause.

### [Comparative Adjective (Unit 6)](/ap-latin/key-terms/comparative-adjective)

Comparatives like *fortior* still agree with their nouns in case, number, and gender. They just use third-declension endings, so the adjective and noun often won't look alike even when they agree perfectly.

## On the AP Exam

Agreement isn't tested as a standalone vocabulary term. It's tested constantly through what you do. On multiple-choice questions, a classic stem asks which noun a given adjective or participle modifies, and the answer always comes down to matching case, number, and gender. On the literal-translation FRQs, scoring guidelines award credit chunk by chunk, and pairing an adjective with the wrong noun costs you the whole segment. With Ovid's *Amores* in Topic 6.4, expect adjectives displaced far from their nouns for poetic effect. Your move on every hard line should be the same: identify each adjective's case, number, and gender, then hunt for the noun that matches all three before you translate anything.

## agreement vs Matching endings

Agreement means matching case, number, and gender, NOT matching letters. Beginners assume agreeing words rhyme (*puella pulchra*), but *nauta bonus* agrees perfectly even though the endings look different, because *nauta* is a masculine first-declension noun. Same trap with third-declension adjectives: *fortis puella* agrees, no rhyme required. Always check the grammar, never the spelling.

## Key Takeaways

- Agreement means a Latin adjective or pronoun matches its noun in three things: case, number, and gender (CED essential knowledge for 6.4.A).
- Agreeing words do not have to have identical endings; *nauta bonus* agrees even though the endings look different, so check grammar, not spelling.
- Latin word order can separate an adjective from its noun by half a line or more, especially in Ovid's poetry, so agreement is your only reliable way to pair them.
- Participles follow the same agreement rule as adjectives, which is the foundation for constructions like the ablative absolute.
- Relative pronouns are the exception worth memorizing: they take number and gender from the antecedent but get their case from their role in their own clause.
- On translation FRQs, pairing an adjective with the wrong noun loses credit for that whole segment, so confirm case, number, and gender before you translate.

## FAQs

### What is agreement in AP Latin?

Agreement is the rule that adjectives, pronouns, and participles must match the noun they modify in case, number, and gender. It's the essential knowledge behind learning objective AP Latin 6.4.A and the skill that lets you decode Latin's flexible word order.

### Do agreeing words in Latin always have the same ending?

No, and this is the biggest agreement trap. *Nauta bonus* ('the good sailor') agrees in case, number, and gender even though *-a* and *-us* don't match, because *nauta* is masculine despite its first-declension form. Third-declension adjectives like *fortis* also rarely rhyme with the nouns they modify.

### How is adjective agreement different from relative pronoun agreement?

An adjective copies all three features (case, number, gender) from its noun. A relative pronoun like *qui* copies only number and gender from its antecedent, while its case is set by its job inside the relative clause. That split is a favorite multiple-choice target.

### Why does Ovid separate adjectives from their nouns?

It's a deliberate poetic technique in elegy, the love-poetry genre covered in Topic 6.4. Separating an adjective from its noun creates emphasis, suspense, or a word picture across the line, and agreement endings are how you reconnect the pair when translating *Amores* 1.9 and 3.1.

### Do participles have to agree with nouns too?

Yes. Participles are verbal adjectives, so they agree in case, number, and gender just like any adjective. That's how an ablative absolute works: a noun and participle agreeing together in the ablative case, like *urbe capta*.
