In AP Latin, word order is a stylistic device where an author rearranges words for emphasis or suspense, including chiasmus (a-b-b-a arrangement), synchysis or interlocking word order (a-b-a-b), and enjambment (delaying a word to the start of the next poetic line).
Latin doesn't need word order to show grammar. Case endings already tell you who's doing what to whom. That frees up word order to do something English can't: carry style and emphasis. When Vergil scrambles the "natural" order of a sentence, he's making a deliberate artistic choice, and the AP exam expects you to name that choice and explain its effect.
The CED spells out three specific word-order patterns. Chiasmus arranges two corresponding pairs in inverted order (a-b-b-a), which creates emphasis by calling attention to that point. Synchysis, also called interlocking word order, weaves elements together in an a-b-a-b pattern to create an unexpected or emphatic moment. Enjambment delays the final word of a phrase, clause, or sentence to the beginning of the next poetic line, building suspense before the payoff word lands. All three show up constantly in the required Aeneid passages, because Vergil treats word placement as part of the meaning.
Word order as a stylistic device has its own learning objective in three separate places: AP Latin 4.2.F (Aeneid Book 1, Topic 4.2), AP Latin 4.3.G (Aeneid Book 2, Topic 4.3), and AP Latin 5.1.G (Aeneid Book 4, Topic 5.1). The course doesn't repeat an objective three times by accident. Recognizing chiasmus, synchysis, and enjambment is a core analytical skill across Units 4 and 5, and it feeds directly into the interpretation objectives (4.3.K through 4.3.Q), where you cite specific Latin and explain how stylistic information supports your reading of the text. Spotting an a-b-b-a pattern is step one. Saying what Vergil gains by it is the actual exam skill.

Anaphora (Units 4-5)
Anaphora is word order's sibling device. Both are covered in the same stylistic-device objectives for Topic 4.2. Anaphora repeats a word at the start of successive phrases to build momentum, while chiasmus and synchysis rearrange words for emphasis. Essay answers often pair them, since Vergil layers repetition on top of unusual word placement in the same passage.
Dactylic Hexameter (Units 4-6)
Word order and meter work together. Vergil has to fit every line into six feet of dactyls and spondees, so where a word falls in the line is shaped by meter, and enjambment only exists because lines have fixed endpoints. When a delayed word spills onto the next line, the meter is what makes that delay feel dramatic.
Dido (Unit 5)
The Book 4 passages in Topic 5.1 (lines 74-89 and 165-197) carry the word-order objective 5.1.G. Vergil's tangled, interlocking arrangements in the Dido episodes mirror her emotional turmoil, which makes these lines prime hunting ground for synchysis examples you can cite in an analytical essay.
Carthage (Units 4-5)
The same passages where you analyze word order are set in Carthage, and the CED ties them to the Punic Wars context (4.2.H). A strong interpretation can connect a stylistic observation about Vergil's Latin to the historical weight Carthage carried for a Roman audience.
Word order shows up on both halves of the exam. In multiple-choice, you might be asked to identify the figure of speech in a quoted line (is the pattern a-b-b-a chiasmus or a-b-a-b synchysis?). In the free-response section, the analytical essay rewards exactly what objectives 4.3.N through 4.3.Q describe. You cite specific Latin words, name the device, and explain how the arrangement supports your interpretation. The trap to avoid is device-spotting without analysis. "Vergil uses chiasmus" earns nothing on its own. "Vergil frames X and Y around Z, throwing emphasis on the central word" is what scores. Always copy out the actual Latin words in the pattern and tie the effect to the meaning of the passage.
Both rearrange paired elements, but the patterns are mirror opposites. Chiasmus is a-b-b-a, where the pairs fold inward like a mirror, creating emphasis at the center. Synchysis is a-b-a-b, where the pairs interlock like woven threads, creating an unexpected or tangled effect. Quick check on the exam: label each element with a letter and read the sequence. If it reverses, it's chiasmus; if it alternates, it's synchysis.
Because Latin case endings carry the grammar, Latin word order is free to carry style, and the AP exam treats unusual word order as a deliberate authorial choice you must analyze.
Chiasmus arranges two corresponding pairs in inverted a-b-b-a order and creates emphasis by drawing the reader's attention to that point.
Synchysis, or interlocking word order, arranges elements in an a-b-a-b pattern to create an unexpected or emphatic moment.
Enjambment delays the final word of a phrase, clause, or sentence to the beginning of the next poetic line, building suspense or emphasis.
Word order has its own learning objective in three required Aeneid topics (4.2.F, 4.3.G, and 5.1.G), covering Books 1, 2, and 4.
On the essay, naming the device is not enough; you have to quote the specific Latin words in the pattern and explain how the arrangement supports your interpretation.
It's the deliberate rearrangement of words for emphasis or suspense. The CED names three specific patterns: chiasmus (a-b-b-a), synchysis or interlocking word order (a-b-a-b), and enjambment (delaying a word to the start of the next line).
Yes, just not for grammar. Because case endings handle who-does-what, word order becomes an artistic tool. Vergil places words for emphasis, surprise, and sound, and the AP exam asks you to explain those choices.
Chiasmus inverts the pairs (a-b-b-a), like a mirror folding inward. Synchysis interlocks them (a-b-a-b), like weaving. Label each word with a letter and read the sequence to tell them apart on the exam.
Enjambment delays the final word of a phrase, clause, or sentence to the beginning of the following poetic line. The line break makes you wait for the key word, creating suspense or throwing extra weight on it when it finally arrives.
It has its own learning objective in three topics: Book 1, lines 88-107 and 496-508 (4.2.F), Book 2, lines 40-56 and 201-249 (4.3.G), and Book 4, lines 74-89 and 165-197 (5.1.G). Expect to analyze it across Units 4 and 5.
