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 Unabridged Based on the Random House Unabridged Dictionary, © Random House, Inc. 2021
