All 36 terms we publish for Style, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.

Juxtaposition
Placing contrasting elements side by side without explicit comment. Douglass: “The sunlight that brought life and healing to you, has brought stripes and death to me.” Effect: lets the contrast make the argument.
Anaphora
Repetition of the same word or phrase at the beginning of successive clauses. Lincoln: “we can not dedicate — we can not consecrate — we can not hallow.” Effect: builds rhythm and intensification toward a claim.
Syntax
Sentence structure. Short sentences create emphasis and urgency; long periodic sentences build suspense before releasing meaning.
Antithesis
Parallel structure holding two opposed ideas in balance. Patrick Henry: “give me liberty or give me death.” Effect: eliminates the middle ground the speaker wants to rule out.
Rhetorical question
A question asked for effect. Its function varies: it can trap an audience (Douglass answers his own), force a definition to be tested (Truth’s “ain’t I a woman?”), or foreclose alternatives. Always specify which.
Syntax as argument
Sentence length and structure carry meaning. A run of short sentences after long ones creates emphasis no word choice can.
Cumulative sentence
Main clause first, then modifiers piling up after it. Feels expansive and observational, and suits description and accumulation of evidence.
Periodic sentence and its payoff
Delays the main clause to the end, holding the reader in suspense. Effective for a single climactic point and exhausting in quantity.
Balanced sentence
Two parallel halves of similar length and structure. Produces an impression of fairness and inevitability, which is why it is common in oratory.
Anadiplosis
Repeating the last word of one clause at the start of the next, building a chain. "Fear leads to anger; anger leads to hate."
Epanalepsis and antimetabole
Epanalepsis repeats a word at the beginning and end of a clause; antimetabole reverses the order of repeated words. "Ask not what your country can do for you" is antimetabole.
Tricolon
Three parallel elements. The most reliable rhythm in English oratory, and the third element carries the weight.
Anaphora at scale
Repetition across many sentences builds cumulative force. Analyze what the repeated phrase makes the audience expect and whether the writer breaks the pattern.
Polysyndeton's effect
Extra conjunctions slow a list and give each item weight. Asyndeton does the opposite, accelerating and suggesting incompleteness.
Sentence fragments as choices
Deliberate fragments create emphasis and informality. In analysis, distinguish a fragment used for effect from an error.
Colon and dash as rhetorical tools
A colon promises what follows; a dash interrupts. Both create a beat that a comma would not, and both are quotable evidence.
Register shift
Moving between formal and colloquial diction. Signals a change in the writer's relationship to the audience and is one of the easiest shifts to locate.
Jargon and its double edge
Technical vocabulary builds ethos with insiders and excludes everyone else. Its use identifies the intended audience precisely.
Euphemism and dysphemism
Softening or sharpening language to reframe. "Collateral damage" and "slaughter" describe the same event and argue opposite conclusions.
Allusion as compressed argument
A reference that imports a whole set of associations in a few words. Its effectiveness depends on the audience recognizing it, which makes it audience evidence too.
Analyzing a shift
Mark where tone, syntax, or diction changes, then say what the change accomplishes. Shifts are the most reliably productive place to look in any passage.
Diction
Word choice. Analyze the connotation and register — "crowd", "mob" and "assembly" describe the same people and evaluate them differently.
Connotation vs denotation
Denotation is the dictionary meaning; connotation is what the word implies. Nearly all diction analysis lives in the gap between them.
Periodic vs loose sentence
A periodic sentence withholds the main clause until the end, creating anticipation; a loose sentence delivers it first and elaborates after.
Parallelism
Repeating grammatical structure across phrases. Creates rhythm and implies the paired ideas are of equal weight.
Asyndeton and polysyndeton
Omitting conjunctions accelerates a list and suggests incompleteness; adding them slows it and suggests accumulation.
Irony
A gap between what is said and what is meant, or expected and actual. Requires shared knowledge, so it also flatters the audience.
Understatement and hyperbole
Understatement can convey control or dry contempt; hyperbole conveys intensity. Both signal a writer's attitude.
Imagery
Sensory language. Makes an abstraction concrete, which is usually pathos operating through detail rather than assertion.
Metaphor and simile
Map the qualities of one thing onto another. Analyzing a metaphor means asking which qualities transfer and which the writer wants ignored.
Personification
Giving human qualities to non-human things, which invites the reader to respond to an abstraction as they would to a person.
Repetition and refrain
Recurring words or phrases that emphasize, unify a text, and lodge an idea in memory.
Shift
A change in tone, subject or perspective, often marked by "but", "yet" or a paragraph break. Locating shifts is how structure gets analyzed.
Active vs passive voice
Active names the actor; passive can obscure responsibility — "mistakes were made" — which is itself a rhetorical choice worth analyzing.
Sentence variety
Mixing lengths and structures controls pace and directs emphasis. Uniform sentences flatten a reader's attention.
Punctuation as a rhetorical choice
Dashes interrupt and emphasize, colons announce, semicolons balance. Each shapes how a sentence is heard.

Practice English Lang

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
