If you’re not sure what hyperbole means, this advertising on the side of a truck I saw today will enlighten you:
XXXXXX’s POOL SERVICE
THE BEST, FASTEST, MOST THOROUGH POOL CLEANING IN THE UNIVERSE
(Who knew swimming pools existed on Alpha Centauri or even on poor, demoted Pluto?)
Incidentally, and sad to say, I once worked with an English teacher who pronounced hyperbole as hyperbowl. I swear. The word is Greek, and the last syllable is pronounced —lee.
