means The sturdy woven jacket-and-pants uniform worn for judo, karate, and other martial arts, usually cinched with a color-coded belt.

from From Japanese 着 (gi), meaning 'clothing' or 'wear,' most commonly seen in compounds like keikogi ('practice clothes') or dogi ('way clothes'). Western martial arts students clipped the word down to just 'gi' sometime in the 20th century as judo and karate spread abroad — a borrowed shorthand for an outfit originally meant simply as plain, functional training dress, not the symbolic battle-armor it became in dojos worldwide.
