KK: /haɪˈpɜr.bə.lɪst/
A person who uses exaggerated statements or claims that are not meant to be taken literally.
The author is known as a hyperbolist, often using extreme exaggeration to make a point in his writing.
Hyperbolist → It is formed from "hyper-" (meaning over or beyond) and "ballo" (from Greek, meaning to throw). The word refers to someone who throws things beyond the truth, often exaggerating or overstating.
Think of someone who 'throws' ('ballo') their statements 'beyond' ('hyper-') the truth — that's why a hyperbolist is someone who exaggerates.
