The common term for scoring zero in tennis is "love". This term is used when a player has not scored any points in a game and indicates a score of 0. The origins of "love" in tennis scoring are debated, though many believe it derives from the French word "l'oeuf," meaning "egg," which symbolizes zero. The unique terminology and scoring system contribute to the sport's charm, with "love" being one of the many terms that reflects tennis's rich history.
