Athleticism → It is formed from "athletic" (from Greek "athletikos", meaning pertaining to athletes or athletic contests) and "-ism" (a suffix used to form nouns indicating a state or condition). The word "athleticism" refers to the condition or quality of being athletic, emphasizing physical fitness and prowess in sports.
Think of 'athletic' relating to athletes and the '-ism' indicating a state or quality — so athleticism is the quality of being athletic.
