AP Latin common mistakes
AP Latin · Understand the traps and how to avoid them.
Translating a passage word-by-word in Latin word order, leaving the English output as a string of unconnected phrases that ignore case endings and verb position, so the sense of the sentence is lost.
Candidates trained on vocabulary lists read left-to-right and treat each Latin word as an English gloss in place, rather than using the inflectional endings (nominative/accusative/ablative, subject-verb agreement) to build clauses.
What to do instead
Before writing English, identify the main verb, then find its subject by matching ending and number, then attach objects and modifiers by case. Practice by marking each noun's case and each verb's person/number on the Latin text first, then translating clause by clause.
On sight-passage multiple-choice questions, choosing an answer because one familiar Latin word appears in it rather than because the option matches the grammatical function or context of the passage.
Under time pressure, candidates pattern-match on vocabulary they recognize and skip the step of checking whether the option actually answers the question asked (e.g., 'what is the case of...' vs. 'what does the author imply...').
What to do instead
Read the stem first and label what type of question it is (grammar, translation, comprehension, scansion). For grammar items, locate the exact form in the passage and parse it before looking at the options; eliminate options that are grammatically impossible for that form.
Misreading poetic word order and hyperbaton in verse passages, treating a noun and adjective separated by several lines as unrelated, or attaching a genitive to the wrong noun.
Candidates apply prose reading habits to poetry, where adjectives, genitives, and prepositional phrases are routinely displaced for meter; they do not scan for agreement across the line break.
What to do instead
When reading verse, first bracket each line and match every adjective to a noun by case, number, and gender, drawing connecting lines on the passage. Practice with short Vergilian and Ovidian lines, explicitly pairing displaced modifiers before translating.
On scansion questions, marking syllable quantities by guessing from English pronunciation or by assuming every vowel before two consonants is long without checking whether the consonants are in the same word and whether the vowel is naturally long or short.
Candidates rely on how Latin 'sounds' rather than applying the rules: position (vowel followed by two consonants or x/z), diphthongs, and natural quantity; they also forget that a final -a is short and final -o often long.
What to do instead
Scan methodically: mark the last foot first (usually a spondee or trochee), identify the dactyls, then work backward. Memorize the position rule and a short list of common naturally long vowels (e.g., ablative -ā, -ō) and diphthongs (ae, au, oe).
In the translation free-response, producing a loose paraphrase that captures the gist but omits specific details (numbers, names, causal connectives, tense distinctions) that the scoring rubric rewards.
Candidates aim for fluent English and drop Latin elements they find awkward, or they compress subordinate clauses, losing points for accuracy of detail.
What to do instead
Translate every clause, keeping connectives (cum, quod, ut) and tense/aspect explicit. After drafting, do a back-check: read each Latin phrase and confirm a corresponding English element exists. Preserve named entities and quantities.
In the essay free-response, summarizing the passage's plot instead of making an analytical argument about how the author uses language, structure, or characterization to achieve an effect, and failing to cite specific Latin.
Candidates default to comprehension-mode retelling because it feels safe, and they are unsure how to move from 'what happens' to 'how and why the author makes it happen.'
What to do instead
Build a thesis that answers the prompt's analytical verb (e.g., 'how does Vergil create sympathy...'), then support each point with a short Latin quotation plus a comment on word choice, sound, or placement. Practice the formula: claim → Latin evidence → analysis of the device → link back to thesis.
Writing an essay with no clear thesis or with a thesis that merely restates the prompt, so body paragraphs list observations without advancing an argument.
Candidates run out of planning time or believe a thesis must be 'objective,' so they avoid committing to an interpretation and default to description.
What to do instead
Spend the first few minutes drafting a one-sentence arguable thesis and an outline of two to three supporting claims before writing. Ensure the thesis makes a claim someone could disagree with, and that each paragraph opens with a topic sentence tied to it.
Quoting Latin inaccurately in the essay-misremembering wording, misquoting case forms, or citing a line that does not actually support the claim-and failing to explain what the quoted words mean.
Candidates quote from memory under time pressure and assume the quotation speaks for itself, so they skip the interpretive step that earns analysis credit.
What to do instead
Quote only short phrases you are confident of, and always follow a quotation with a translation and an explicit statement of its effect. If unsure of exact wording, describe the Latin precisely (e.g., 'the repeated -ōrum endings') rather than inventing a quotation.
On the syllabus-based multiple-choice items, confusing characters, speeches, or book/line context across the required reading, attributing a speech to the wrong speaker or a scene to the wrong book.
Candidates memorize isolated vocabulary and translation but not the architecture of each work-who speaks when, in which book, to whom, and why-so context questions collapse.
What to do instead
Build a one-page map of each work: sequence of episodes, speakers, and key lines, with a short note on each speech's purpose. Review by quizzing yourself on 'who says this and in what situation' rather than rereading translations.
Managing time poorly: spending too long on early multiple-choice grammar items or writing an overlong essay that leaves no time to proofread, resulting in unfinished sections or unchecked errors.
Candidates treat every question as equally weighted and over-invest in difficult items, and they write essays without budgeting for planning and revision.
What to do instead
Set a per-question time target for the multiple-choice section, flag and skip hard items to return to, and for the essay allocate fixed minutes to outline, draft, and a final proofread for thesis clarity, Latin accuracy, and completeness of the argument.
