AP English Literature – Close Reading Strategies (Annotation, TP?CASTT, DIDLS)

What This Is

Close?reading is the disciplined practice of reading a literary excerpt with a microscope—you annotate every word, track shifts in tone, and decode the author’s craft. On the AP English Literature exam you’ll be asked to write a timed literary analysis (Free?Response Question) that demonstrates you can unpack a passage, not just summarize it. Think of the opening paragraph of F. Scott?Fitzgerald’s The Great Gatsby (“In my younger and more vulnerable…”)—a few sentences that reveal narrator reliability, era?specific diction, and the novel’s central theme of the American Dream. Mastering annotation, TP?CASTT, and DIDLS lets you turn that dense paragraph into a clear, thesis?driven essay.


Key Terms & Devices

  • Annotation – Writing brief notes in the margins (definitions, questions, connections). Ex: circling “gilded” and writing “suggests false shine.”
  • TP?CASTT – A six?step poem?analysis acronym (Title, Paraphrase, Connotation, Attitude, Shift, Theme). Used for any short literary excerpt.
  • DIDLS – A five?step prose?analysis acronym (Diction, Imagery, Details, Language, Sound).
  • Diction – Word choice that reveals tone or character. Ex: “savage” vs. “ferocious.”
  • Imagery – Sensory language that paints a picture. Ex: “the bitter cold of the night wrapped around him.”
  • Connotation – The emotional or cultural “baggage” a word carries. Ex: “home” evokes safety, nostalgia.
  • Attitude (Tone) – The author’s stance toward the subject. Ex: sarcastic, reverent, mournful.
  • Shift – A change in speaker, setting, or tone that signals a new idea. Ex: “But now…” in a poem.
  • Theme – The underlying universal idea the work explores. Ex: “the corrupting power of ambition.”
  • Symbol – An object that stands for a larger concept. Ex: the green light in Gatsby = hope/illusion.
  • Allusion – A reference to another text, myth, or historical event. Ex: “a modern Prometheus” in a contemporary novel.

Step?by?Step / Process Flow

  1. Read the passage once, silently. Let the language settle; note any immediate emotional reaction.
  2. Annotate actively. Underline key diction, circle unfamiliar words, jot marginal questions, and mark shifts (?).
  3. Apply TP?CASTT (or DIDLS) in a quick notebook table.
  4. Title: Predict meaning.
  5. Paraphrase: Write a one?sentence prose summary.
  6. Connotation: List at least three loaded words and their implied meanings.
  7. Attitude: Note the speaker’s tone with a single adjective.
  8. Shift: Identify where the tone or perspective changes.
  9. Theme: State the central idea in a concise phrase.
  10. Craft a thesis statement. Combine the author’s choice + effect + how it supports the theme (e.g., “Fitzgerald’s use of glittering, metallic diction creates a veneer of wealth that ultimately exposes the emptiness of the American Dream”).
  11. Outline body paragraphs. Each paragraph should:
  12. Begin with a topic sentence that ties back to the thesis.
  13. Cite a specific textual detail (line number or quotation).
  14. Explain why that detail matters (author’s purpose, effect on reader).
  15. Write, then revise. In the final minutes, check that every claim is backed by evidence and that you have not slipped into summary.

Common Mistakes

  • Mistake: Summarizing the plot instead of analyzing language.
    Correction: Focus on how the author says something (diction, imagery, structure), not what happens.

  • Mistake: Treating “tone” and “mood” as interchangeable.
    Correction: Tone = author’s attitude; Mood = reader’s emotional response. Identify both when relevant.

  • Mistake: Leaving the “Shift” step blank.
    Correction: Look for transition words (“however,” “yet”) or a sudden change in imagery; a shift often signals a new argument in the passage.

  • Mistake: Using vague words like “good” or “bad” to describe diction.
    Correction: Choose precise adjectives (e.g., “clinical,” “saccharine,” “abrasive”) and explain their connotative impact.

  • Mistake: Cramming too many quotations.
    Correction: One well?explained quote per paragraph is enough; the rest can be paraphrased while still referencing the line number.


AP Exam Insights

  1. Free?Response Prompt Types – The 2019?2024 FRQs often ask you to “analyze how the author develops a theme” or “explain how the writer’s use of literary devices contributes to meaning.” Your TP?CASTT/DIDLS notes give you ready?made evidence.
  2. Scoring Rubric Tip: The “Evidence and Commentary” category (0?6 points) rewards specific textual references plus insightful analysis. A single, well?explained image can earn more points than several shallow observations.
  3. Tricky Distinctions:
  4. Simile vs. Metaphor: Simile uses “like” or “as”; metaphor asserts identity.
  5. Rhetorical Question vs. Hypophora: A rhetorical question asks without expecting an answer; hypophora asks then immediately answers.
  6. Time Management: You have 40 minutes for the FRQ. Spend ~5 minutes on TP?CASTT/DIDLS, 5 minutes on thesis, 25 minutes writing (?3 paragraphs), and 5 minutes revising.

Quick Check Questions

  1. Multiple?Choice: In Emily Dickinson’s “Because I could not stop for Death,” the line “The carriage held but just ourselves” most clearly illustrates which device?
  2. A) Alliteration
  3. B) Symbolism
  4. C) Hyperbole
  5. D) Personification
    Answer: B) Symbolism – the carriage represents the journey toward death.

  6. FRQ?Style Prompt: Read the excerpt from The Great Gatsby (pages 23?24). Write an essay that explains how Fitzgerald’s diction and imagery develop the theme of illusion versus reality.
    Answer Sketch: Thesis – Fitzgerald’s choice of “golden,” “gleaming,” and “bright” diction paired with the image of the “green light” creates a shimmering illusion that masks the emptiness of the characters’ lives, reinforcing the novel’s critique of the American Dream.

  7. Multiple?Choice: Which of the following is NOT a component of the DIDLS acronym?

  8. A) Diction
  9. B) Imagery
  10. C) Dialogue
  11. D) Sound
    Answer: C) Dialogue – DIDLS includes Diction, Imagery, Details, Language, Sound.

Last?Minute Cram Sheet

  1. Don’t summarize – always tie a textual detail to the author’s purpose.
  2. TP?CASTT = Title, Paraphrase, Connotation, Attitude, Shift, Theme.
  3. DIDLS = Diction, Imagery, Details, Language, Sound.
  4. Quote?sandwich: Introduce-Quote-Explain-Link to thesis.
  5. Tone vs. Mood – tone = author’s attitude; mood = reader’s feeling.
  6. Shift signals a new argument; look for transition words or a change in imagery.
  7. Connotation matters more than denotation for AP analysis.
  8. Symbol = concrete object-abstract idea (e.g., the scarlet letter “A”).
  9. One?paragraph rule: Each body paragraph must contain ONE clear claim, ONE quote, ONE analysis.
  10. Time tip: 5?5?25?5 minutes (TP?CASTT-Thesis-Write-Revise).
