In to Tell the Truth but tell it slant what literary device is used in line seven?

The literary device used in line seven of Emily Dickinson's poem "Tell all the Truth but tell it slant" is metaphor.

Here's why:

* Line seven: "Success in Circuit lies"

* Metaphor: Dickinson uses the word "Circuit" to represent a roundabout or indirect way of telling the truth. It's not a literal circuit, but a metaphorical one, implying that truth is best revealed gradually and subtly, not in a direct, head-on way.

Let me know if you'd like a deeper analysis of any other lines from the poem!
