Etymology

Origin of sumo

1895–1900; < Japanese sumō, earlier suma(f )u to wrestle

Explanation

Sumo is a Japanese wrestling style in which opponents try to force each other out of a ring. Sumo wrestlers are known for being enormous. The wrestlers live together and follow ancient traditions like growing their hair and wearing robes. Sumo wrestling is an ancient Japanese sport that follows traditional rituals, such as tossing salt into the ring before a match to cleanse it, or even the manner of dress, in which giant men wear only small loincloths. In sumo wrestling, the two opponents grapple with the goal of pushing each other out of the ring or to the mat. The word sumo literally means "to mutually rush at," though it's used to mean simply "to compete."
