The term "Perk" encompasses a wide range of meanings, from geographical locations to notable individuals and common concepts. Most commonly, it refers to an employee benefit—a non-wage compensation or "perquisite"—or a special ability bonus granted to a character in video games. Significant figures include August Perk (1897–1945), a German anti-Nazi resistance fighter, and American politician Ralph Perk (1914–1999). It also served as a nickname for professional athletes like NHL player Percy Galbraith and NBA star Kendrick Perkins. Beyond people and common terms, "Perk" identifies a village and castle in Belgium, an Antarctic summit, and tetrachloroethylene, a chemical notably used for dry-cleaning.
