ὑπερβολή
hyperbole
Ancient Greek
“The Greeks named their word for exaggeration after the act of throwing something too far — and mathematicians later borrowed it for a curve that never quite arrives.”
In Ancient Greek, hyperbolē (ὑπερβολή) meant 'a throwing beyond' — from hyper ('over, beyond') and ballein ('to throw'). Aristotle used the word in his Rhetoric around 335 BCE to describe the figure of speech where a speaker throws the truth beyond its natural limit. When you said something was hyperbolē, you meant the claim had overshot the facts.
The Romans adopted the term directly. Quintilian, writing his Institutio Oratoria around 95 CE, catalogued hyperbole alongside irony and metaphor as one of rhetoric's standard tools. He warned students that hyperbole works only when both speaker and audience know the statement is untrue. Say 'he ran faster than the wind' and everyone nods. Say 'he ran faster than light' and you've lost them.
English borrowed hyperbole from Latin in the 1520s. The word kept its rhetorical meaning unchanged across two thousand years. Meanwhile, mathematicians took the same Greek root and created 'hyperbola' — a conic section where the curve 'throws beyond' the cone's boundary, approaching but never touching its asymptotes.
The rhetorical figure and the mathematical curve share more than a root. Both describe something that exceeds its expected boundary. Both involve a trajectory that overshoots. The difference is that in math, the overshoot is precise and eternal; in speech, it's temporary and everyone knows it. Or at least they used to.

People now say 'that's literally hyperbole' without noticing the paradox. The word that names exaggeration has itself become casual — tossed around in arguments, tweets, and media criticism as if Aristotle were still grading the class.
But the throwing metaphor holds. Every exaggeration is a projectile that overshoots the truth on purpose. The skill is knowing how far to throw. Too little and nobody notices. Too much and nobody believes you. Quintilian understood this in 95 CE. Social media has not caught up.
