In AP Latin, person is the property of a verb (shown by its ending) that tells you who the subject is: first person (I/we), second person (you), or third person (he, she, it, they). Reading person correctly is how you know amō means "I love" but amat means "he loves," even with no subject written.
Person is one of the five things every finite Latin verb tells you, along with number, tense, voice, and mood. It answers the question "who is doing this?" First person means the speaker (I or we), second person means the one being addressed (you), and third person means anyone else (he, she, it, they). Latin packs this information into the verb ending itself: -ō/-m, -s, -t, -mus, -tis, -nt in the active voice. That's why Latin can drop subject pronouns entirely. The ending already did the work.
For the AP exam, person isn't just a chart to memorize. It's a reading tool. Since Latin word order is flexible and subjects are often omitted, the personal ending is frequently your only clue about who the subject is. It also carries literary weight in the Unit 1 Catullus poems, where the poet constantly switches person: talking about himself in the third person, commanding himself in the second person, confessing in the first. Spotting those shifts is exactly the kind of grammar-to-meaning move the exam rewards.
Person sits at the heart of learning objectives 1.1.C, 1.2.C, and 1.3.C, which all ask you to describe how grammar contributes to meaning in context. The essential knowledge for these objectives says it directly: Latin verbs indicate person, number, tense, voice, and mood. In Unit 1's Catullus readings, person does double duty. First, it's mechanical: you can't translate accurately without it. Second, it's interpretive. Catullus 8 famously opens with the vocative "miser Catulle" and then pivots to second-person commands aimed at himself ("quod vides perisse perditum ducas"). That grammatical split, the poet talking to himself as "you," creates the poem's whole drama of self-control versus heartbreak. When a question asks what a grammatical choice contributes to meaning, person shifts like this are a classic answer. For the full poems and context, head up to the topic guides for 1.1 (Catullus Love Poems), 1.2 (Social and Personal Poems), and 1.3 (Catullus 64).

Imperative Mood (Unit 1)
Imperatives are second person by definition, since you can only command someone you're addressing. When Catullus orders himself to "perfer, obdura" (endure, hold firm), the imperative mood and second person work together to dramatize him coaching himself.
Infinitive (Unit 1)
The infinitive is the opposite of a personal verb form. It has tense and voice but no person, which is why it's called non-finite. In indirect statement you have to recover the subject from an accusative noun instead of a verb ending, a skill translation questions love to test.
Perfect Tense (Unit 1)
The perfect tense has its own set of personal endings (-ī, -istī, -it, -imus, -istis, -ērunt), different from the present system. To translate a form like "perisse" or "fuit," you read tense and person off the same ending, two pieces of information stacked in one form.
Relative Clauses (Unit 1)
The verb inside a relative clause agrees in person with the antecedent of the relative pronoun. So in a clause like "ego, qui amō," the verb is first person because the antecedent is "ego." Miss that agreement and the whole clause translates wrong.
Person shows up two ways. First, as straight grammar identification: multiple-choice and short-answer questions ask what a verb's ending tells you, or who the unstated subject of a verb is, and you answer by reading person and number off the ending. Released short-answer questions on prose passages (like the 2018 Caesar selections) routinely hinge on tracking who is doing what when no subject noun appears. Second, as analysis. Practice questions on Catullus 8 ask what the shift from the vocative "miser Catulle" to second-person self-commands accomplishes, and the answer is about person: Catullus splits himself into speaker and addressee. On the translation FRQ, getting person wrong (translating "ducas" as "he considers" instead of "you should consider") loses points even if every vocabulary word is right. So your job is twofold: decode person mechanically every time, and be ready to explain what a person shift does to the poem's meaning.
Person and number are bundled into the same verb ending, so they're easy to blur together. Person tells you WHO the subject is relative to the speaker (I, you, or someone else). Number tells you HOW MANY (singular or plural). "Amās" is second person singular (you love); "amātis" is second person plural (y'all love). Same person, different number. When a question asks you to identify a verb form fully, you need both, and they're separate answers.
Person is the verb property that identifies the subject as first person (I/we), second person (you), or third person (he/she/it/they).
Latin shows person through verb endings (-ō/-m, -s, -t, -mus, -tis, -nt), which is why subject pronouns are usually omitted.
Person and number are different things packed into one ending: person says who, number says how many.
Non-finite forms like infinitives and participles have no person, so you have to find their subject elsewhere in the sentence.
In Catullus 8, the shift from vocative address to second-person commands turns the poet into his own audience, a textbook example of grammar creating meaning under LOs 1.1.C, 1.2.C, and 1.3.C.
On translation FRQs, mistranslating person (rendering "you" as "he") costs points even when the vocabulary is correct.
Person is the feature of a finite verb that tells you who the subject is: first person means the speaker (I/we), second person means the one addressed (you), and third person means someone or something else. Latin marks it with verb endings like -ō, -s, -t.
No. Person tells you who the subject is (I, you, or a third party), while number tells you whether the subject is singular or plural. The ending -s in "amās" gives you both at once: second person AND singular.
No. Infinitives, participles, and gerunds are non-finite forms, meaning they carry no person marking. In an indirect statement like "dīcit Catullum amāre," the subject comes from the accusative "Catullum," not from the infinitive's ending.
In Catullus 8, he addresses himself with the vocative "miser Catulle" and then issues second-person commands like "ducas" and "obdura." The grammatical split lets him play both the strict coach and the heartbroken lover, which is exactly the kind of grammar-meaning connection AP questions ask about.
You'll identify the person of verb forms in multiple-choice and short-answer questions, supply the right English subject when Latin omits it, and translate person accurately on the literal-translation FRQ. Analysis questions may also ask what a shift in person contributes to a passage's effect.
