A wiki is a type of website whose contents can be edited from the web browser, and which keeps a version history for each editable page. Wikis are often, but not always, editable by any visitor to the site.
- wiki (as an adjective), "the wiki way", and the antonym un-wiki are also used to describe the community-oriented philosophy that goes with such a system (e.g. "that's not a very wiki way of doing things").
- Wiki (with a capital 'W') is an incorrect term, although it has sometimes been used to refer to either Wikipedia or the Portland Pattern Repository (also known as WikiWikiWeb), which was the first wiki to be created.
- wiki software and wiki engine are terms referring to pieces of software that power wiki websites. There are many different types of wiki software; some very simple, others with advanced features.
