English 'irony' descends through Latin 'ironia' from Greek 'eirōneía,' rooted in 'eirōn' (the comic dissembler who feigns ignorance), itself likely from 'eirein' (to speak), connecting to PIE *wer- and making irony a distant etymological cousin of 'word,' 'verb,' and 'rhetoric.'
Definition
A rhetorical device or situation in which the intended meaning is opposite to the literal sense of the words used, or in which an outcome is contrary to expectation, deriving from Greek eirōneía (feigned ignorance), itself from the PIE root *werh₁- (to speak).
The Full Story
Greek5th century BCEwell-attested
The word 'irony' enters English from Latin 'ironia', itself borrowed from Ancient Greek 'εἰρωνεία' (eirōneía), meaning 'dissimulation, feigned ignorance'. TheGreek term derives from 'εἴρων' (eírōn), the stock character in Attic comedy who defeats the boastful 'ἀλαζών' (alazṓn) through deliberate self-deprecation and pretended ignorance. Aristotle discussed the eírōn in both the Rhetoric

TheGreek 'eirōn' — ancestor of 'irony' — likely shares its ultimate PIE root *wer- ('to speak') with the English word 'word' itself. This means that 'irony' (sayingone thing andmeaning another) and 'word' (the basic unit of saying anything at all) are etymological relatives. The capacity for deception was never a corruption of language; it was baked
of speech itself. Some scholars trace this further to the Proto-Indo-European root *wer- ('to speak, to say'), which also gives rise to English 'word' (from Proto-Germanic *wurdą), Latin 'verbum' ('word', yielding English 'verb', 'verbal', 'proverb'), and Greek 'ῥήτωρ' (rhḗtōr, 'orator', yielding English 'rhetoric'). The semantic journey is remarkable: from a PIE root meaning simply 'to speak', Greek developed a term for a specific kind of deceptive speech, which Latin narrowed to a rhetorical device, and English expanded into multiple registers — verbal irony (saying the opposite of what one means), dramatic irony (audience knowledge exceeding characters'), and situational irony (outcomes contradicting expectations). The Romantic period, particularly Friedrich Schlegel's concept of 'Romantic irony', further broadened the term to encompass artistic self-awareness and philosophical detachment. Key roots: εἴρων (eírōn) (Ancient Greek: "dissembler, one who says less than he thinks"), εἴρω (eírō) (Ancient Greek: "to speak, to say"), *wer- (Proto-Indo-European: "to speak, to say").
