What this topic is asking

Topic 5.4 deepens the work on Figurative Language (FIG), focusing on metaphor and especially the extended metaphor or conceit. In Unit 2 you read simile and metaphor at the level of a single comparison. Now the College Board (skill FIG-6.B) asks you to read a metaphor that is sustained across a whole poem, where one comparison is developed stage by stage. The skill is to read what each part of the comparison contributes, and how the metaphor builds meaning as it extends.

Tenor, vehicle, and the metaphor

In a single metaphor, the comparison lands once. In an extended metaphor, the poet returns to the vehicle and develops it, so the reader tracks the tenor through every stage of the image. Each new detail of the vehicle is a new claim about the tenor.

Every part of the vehicle does work

The conceit as structure

Because an extended metaphor unfolds across a poem, it often provides the poem's structure: the stages of the vehicle become the stages of the poem. A friendship-as-garden poem may move from planting to overgrowth as its very shape. Reading the conceit and the structure together, how the development of the image organizes the poem, is a strong, integrated analytic move.

Reading an extended metaphor

Why this matters for the exam

Metaphor and the extended metaphor appear on the multiple choice section (questions ask you to identify a conceit and read its parts) and frequently organize the poetry analysis essay (Free Response Question 2). When a poem turns on an extended metaphor, reading each part of the vehicle, rather than naming the comparison once, is the move that earns the upper rubric points and often the sophistication point.

Try this

Q1. What is an extended metaphor (conceit)? [Recall]

  • Cue. A single metaphor developed across many lines or a whole poem, in which the vehicle is sustained and elaborated so that each part of the image carries meaning about the tenor.

Q2. A poem figures a life as a single day, from dawn to dusk. How would you analyze this extended metaphor? [Short explanation]

  • Cue. Read each stage of the day as a stage of the life, dawn as birth or youth, noon as prime, dusk as age, and show how the development of the day-vehicle structures the poem, so the analysis reads every part of the comparison rather than naming it once.

AP 2024 (multiple choice, style)1 marksAcross a whole poem the speaker develops the idea that a friendship is a garden: planted, tended, weathered, and finally overgrown. This sustained comparison is best called (A) a simile (B) an extended metaphor that traces the friendship's whole life through the garden (C) personification (D) an allusion (E) a literal account of gardening.
Show worked answer →

Answer: (B). The skill is recognizing an extended metaphor and reading what it contributes.

The garden is not compared once but developed across the poem, planted, tended, overgrown, so the comparison is an extended metaphor that maps the friendship's whole life onto the garden's. Each stage of the garden carries a stage of the friendship.

Why not the others: (A) a simile uses "like" or "as" and is usually brief; (C) and (D) the poem personifies and alludes to nothing here; (E) the garden is figurative throughout.

Markers reward students who identify an extended metaphor and read what each part of the comparison contributes.

AP 2023 (poetry analysis, style)6 marksRead carefully the following original poem in which the speaker figures grief as a house they are slowly closing up, room by room. Then write a well-developed essay analyzing how the poet uses the extended metaphor to develop the poem's meaning.
Show worked answer →

Free Response Question 2 (poetry analysis), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication).

Thesis (1 point): claim what the conceit does, e.g. "By figuring grief as a house closed room by room, the poet renders mourning as a slow withdrawal from a life once fully lived."

Evidence and commentary (4 points): tie each stage of the metaphor, each closed room, to the stage of grief it carries, explaining the effect.

Sophistication (1 point): show how the house metaphor holds both the diminishment and the strange order of grieving.
