Fiercer → It is formed from "fierce" (from Old French *fier*, meaning proud or fierce) and the comparative suffix "-er" (meaning more). The word "fiercer" means more fierce or exhibiting greater intensity of fierceness.
Think of someone being 'more fierce' — the suffix '-er' indicates a comparison, while 'fierce' describes a strong, intense quality.
