7.C Naming a Device vs Explaining Its Effect
Naming a device just proves you can spot it. The real work is explaining what that device does to meaning, so every claim needs a sentence that says what the device produces, not just what it's called.
Calling something a metaphor or an example of alliteration is an observation, not an argument. Anyone reading the text can see the device is there once you point to it. What they cannot see without you is what the device does: how it shapes the reader's sense of time, guilt, confinement, or whatever the essay is arguing. An effect sentence closes that gap. It takes the device and ties it to a specific consequence for meaning, usually by finishing the thought the device only starts.
The move is mechanical once you see it. Start with the naming sentence: 'the poet uses alliteration in line 9.' Then ask what the repeated sound actually does to the words it binds together. If the line is 'the slow stone settles' and the essay argues the poem makes time visible, the next sentence says the alliteration fuses the three words into one drawn-out sound, so the line is heard as a single slow motion rather than three separate actions. That sentence earns its place because it serves the claim; the naming sentence alone does not.
This is why an opening paragraph stuffed with devices is weaker than one built on interpretation: a list of labels has no claim to attach to, so there is nothing for evidence to serve. It also means a correctly spotted device can still fail if it does no work for your argument. A ship simile that only describes a house's size, in an essay about unreliable memory, should be cut, however accurate the label. Evidence is chosen on purpose, not just noticed.

Watch it explained
- How it worksHow does an effect sentence connect a device to the meaning it produces in a reader?
- How it worksWalk me through moving from the poet uses alliteration to what that alliteration actually accomplishes.
- Worked exampleShow me a device-spotting sentence and an effect sentence written about the same image of a locked door.
- Common mistakeWhy isn't a list of devices in your opening a stronger start than an interpretation?
- Going furtherWhat changes when the device you named turns out to do nothing your claim needs?
