What is "deaflympics"

n. A sports competition held every two years for deaf people.

The Deaflympics (previously called World Games for the Deaf, and International Games for the Deaf) are an International Olympic Committee (IOC)-sanctioned event at which deaf athletes compete at an elite level. Unlike the athletes in other IOC-sanctioned events (the Olympics, the Paralympics, and the Special Olympics), the Deaflympians cannot be guided by sounds (e.g., the starter's guns, bullhorn commands or referee whistles). The games have been organized by the Comité International des Sports des Sourds (CISS, "The International Committee of Sports for the Deaf") since the first event.
