You probably can guess that the second half of Wikipedia’s name is derived from “encyclopedia” as the website acts as an open-source reference for nearly every topic imaginable. But do you know where “wiki” comes from?
Let’s go straight to the source to find out. According to Wikipedia, a wiki is “a web application which allows people to add, modify, or delete content in collaboration with others."
The term "wiki" on its own was coined by programmer Ward Cunningham from the Hawaiian phrase wiki-wiki meaning "quick-quick."
Therefore, wiki + encyclopedia = Wikipedia.
