What is the contribution of the extended metaphor in the poem "Fog" ?
The poem extends the comparison of fog to a cat throughout — it 'comes on little cat feet', 'sits looking over harbor and city on silent haunches', and then 'moves on'. This extended metaphor vividly captures the fog's silent, soft, and stealthy arrival and departure, making an abstract natural phenomenon concrete, visual, and memorable through simple, economical language.
Marking Scheme
- 11 mark: correctly identifies the extended metaphor — fog compared to a cat, sustained through 'little cat feet' and 'silent haunches'.
- 21 mark: explains the qualities/effect conveyed — silent, soft, stealthy, unpredictable arrival and departure of fog.
- 31 mark: notes the contribution to the poem overall — vivid imagery, economy of words, and unity/consistency of the single sustained image (Imagist technique).
Hint
Don't just identify the metaphor (fog = cat); explain what qualities it conveys — silence, softness, stealth — and how sustaining it through both stanzas unifies the poem.
Quick Oral Answer
The extended metaphor compares fog to a cat throughout the poem — silently arriving, sitting quietly, and moving on — which makes the fog's soft, stealthy, unpredictable nature vivid and memorable in very few words.
Analysis & Explanation
The single extended cat-metaphor gives 'Fog' its unity, vivid imagery, and economy of expression.
Concept
- Carl Sandburg's 'Fog' is built entirely on one sustained metaphor comparing fog to a cat, carried through its arrival, pause, and departure across both lines/stanzas.
Contribution
- Creates vivid, concrete sensory imagery for an intangible, formless natural phenomenon.
- Reinforces the poem's mood of quietness, stealth, and transience through the cat's characteristic silent movement.
- Achieves economy of expression — a complete visual and emotional impression in minimal words, exemplifying Sandburg's Imagist technique.
Common Mistakes
- Merely stating 'fog is compared to a cat' without explaining WHAT the comparison contributes — the qualities of silence, softness, and quiet control it conveys, and why sustaining it strengthens the whole poem.
Common Mistakes
- 1Merely stating 'fog is like a cat' without explaining the specific qualities (silence, softness, stealth) this comparison conveys.
- 2Confusing metaphor with simile, since the poem uses 'like' nowhere yet is often mislabelled as a simile in student answers.
- 3Not addressing 'contribution' — i.e., failing to explain HOW the extended metaphor enhances imagery, mood, and economy rather than just identifying it.
