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.
Agreement is the matching system that holds a Latin sentence together. An adjective or pronoun must share three things with the noun 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 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.
Agreement lives in Topic 6.4 (Ovid, Amores 1.9 and 3.1) under learning objective AP Latin 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 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.

Participle (Unit 6)
Participles are verbal 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)
The ablative absolute 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)
Relative pronouns 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)
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.
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 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.
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.
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.
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.
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.
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.
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.
