Etymology: The Greek "adunaton" meant simply "an impossibility," and the word was built from a negation stacked on a verb of ability. Its root is "dunasthai," "to be able," which also gave Greek "dunamis," meaning power or strength. Add the alpha privative "a-," meaning "not," and the adjective "adunatos" means "unable" or "impossible." Turning that adjective into a neuter noun with the ending "-on" produced the thing itself: the impossible, as a category you could name. Latin borrowed the Greek term, and English took it from there as a technical term of rhetoric. Its use is in the sense of a figure of speech, the rhetorical device in which a speaker claims something will happen only when some impossible event occurs, such as rivers flowing backwards. The word does not describe an impossibility in the everyday sense. It names a deliberate exaggeration that uses the impossible to make a point hit harder.
