noun

el deporte

sport

Actividad física o juego que se hace siguiendo ciertas reglas para mejorar el cuerpo o competir por diversión o premios.

Deporte means sport: a physical activity or game practiced for exercise, recreation, or competition, usually with rules.

It can also refer to sport in general as a field of activity or entertainment.

Gender: masculine — el deporte
Plural: los deportes
It comes from an older Spanish word meaning “amusement” or “recreation,” related to the verb deportar , which originally included the sense “to divert or amuse.”

actividad física — “physical activity”; broader than deporte, since it includes activities such as walking that are not necessarily sports.
ejercicio — “exercise”; emphasizes physical effort and fitness rather than rules or competition.
juego — “game”; can overlap with deporte, but also includes nonphysical games.

There is no exact antonym. sedentarismo , meaning “a sedentary lifestyle,” contrasts with the physical activity involved in sport.
