ironyyoudaoicibaDictYouDict[irony 词源字典]
irony: [16] Irony has no etymological connection with iron. It comes via Latin īrōnia from Greek eirōneíā, which signified ‘deliberately pretending ignorance, particularly as a rhetorical device to get the better of one’s opponent in argument’. This was a derivative of eírōn ‘dissembler’, which in turn came from the verb eírein ‘say’. This original sense of ‘dissimulation’ survives in the expression Socratic irony, a reference to Socrates’ use of such feigned ignorance as a pedagogical method, but it has been overtaken as the main sense of the word by ‘saying the opposite of what one means’.
