This page is a list of prefixes used to create interwiki links in articles in A Fifth Dimension. Interwiki prefixes enable us to conveniently produce external links to sister projects, such as Wikipedia, Wiktionary or Wikia. Such external links are often used to help "fill in the gaps" that may be left in information contributed to our wiki. For instance, when wanting to provide the definition of a word that does not deserve a full encyclopedic article in A Fifth Dimension, you may just create a link to the word's entry on Wiktionary. It also helps to speed up adding external links and references involving such projects.
