"Wiki Word
A wiki word is the basis of more wiki wiki web processing engines and the easiest way to create linked content on a wiki page.
A standard WikiWord is two words pressed together with no spaces and each major word is caiptailized.
A more complex version of a wiki word allows for more descriptive text. This version uses double square brackets to enclose the wiki word and a text string separated by a colon (:).
This more complex example is also more forgiving, as it will create wiki words out of the first part of the text, even if that text is not a properly formatted wiki word and it also allows a text description that has nothing to do with the wiki word, this is great for accronyms."
