A WikiWord is made up of two or more concatenated words with uppercase letters (this is often also referred to as CamelCase?). If you write a word this way into a page of the WikiWikiWeb, you create a new HyperLink?.

These are valid WikiWords for example:

• RunCapitalizedWordsTogether?
• EditThisPage
• ThisIsAWikiWordAsWell?

while those are not:

• IBM
• somewordswithoutuppercaseletters
• 123456789

You can also create HyperLink?s inside your WikiWikiWeb which are not made up of WikiWords by using square brackets:

• [This is a sentence in square brackets which becomes a Hyperlink?]
• [I'm a link too?]

Sometimes you must be a bit creative to invent nice and talking WikiWords, but this can also be very funny.
