Lit. Elements

Epigram: a short poem or verse that seeks to ridicule a thought or event, usually with witticism or sarcasm
Example: “Sir, I admit your general rule,
That every poet is a fool,
But you yourself may serve to show it,
That every fool is not a poet.” -Samuel Taylor Coleridge

Ambiguity: an expression whose meaning cannot be determined from its context, or open to two or more interpretations
Example: And then a plank in reason, broke,
And I dropped down and down--
And hit a world at every plunge,
And finished knowing--then--
[she lost conciousness]
[she ended up finding out something]
[she did not know anything anymore] -Emily Dickinson
