irony

Irony goes back to Ancient Greek εἰρωνεία, eironeia, meaning dissimulation or affected ignorance. The noun was tied to the eiron, a character who hid his strength behind understatement. In 5th-century BCE Greek comedy, that figure won by seeming weaker or duller than he was. The word already carried a tone of strategy rather than simple wit.

Athens gave the term a philosophical turn through Socrates in the late 5th century BCE. His questioning style looked like ignorance, but it exposed the ignorance of others. Plato did not coin the noun, yet the social scene around Socrates fixed the idea in memory. By the Roman period, Latin had ironia as a rhetorical term.

From Latin ironia the word passed into French as ironie and into English in the 16th century. English first used irony for a figure of speech in which the literal words and intended meaning did not match. Writers and critics then widened it to situations, character types, and historical reversals. The meaning moved from feigned ignorance to layered contradiction.

Modern irony now covers verbal irony, dramatic irony, and situational irony. The newer casual use often means an unexpected mismatch, though stricter usage keeps the contrast between surface and underlying meaning. That breadth has stretched the word, but not erased its core. Irony still turns on a gap between what appears and what is.
