forceful
UK: ˈfɔːsf(ə)l | US: ˈfɔːrsf(ə)l
adj. powerful and assertive in effect or action
adj. (of a person) strong-willed or determined
The word "forceful" combines "force," derived from Old French force (strength, power), itself from Latin fortis (strong), with the suffix "-ful," from Old English -full (full of). The suffix "-ful" transforms nouns into adjectives, indicating abundance or possession of the root's quality. Thus, "forceful" literally means "full of force," evolving to describe actions or people exhibiting strength or determination.
