Definition of wiki in US English:



  • A website that allows collaborative editing of its content and structure by its users.

    • ‘We can also collaborate via private blogs and wikis.’
    • ‘There are instructions on the report website on how to request access to the wiki.’
    • ‘And I have a sneaky suspicion that the same goes for most other examples of participative media, from blogs to tags to wikis to whatever.’
    • ‘Blogs, wikis and other forms of online discourse are individual interactions, not corporate communications.’
    • ‘At the heart of this movement are wikis, web sites that allow users to directly edit any web page with one click of the mouse.’
