Etymology

Origin of wiki

First recorded in 1990–95; shortening of WikiWikiWeb, a software program developed by Howard G. “Ward” Cunningham (born 1949), U.S. computer programmer; from Hawaiian wikiwiki “very quick,” emphatic reduplication of wiki “quick.” Cunningham coined the name WikiWikiWeb after recalling that a Honolulu International Airport counter employee advised him to take the Wiki Wiki Shuttle (a shuttle bus that runs between the terminals of the airport); his original idea was to make WikiWikiWeb's pages readily editable by its users and initially thought about calling his program QuickWeb but changed his mind and named it WikiWikiWeb
