I want to internally add a reference to a wiki-page. For example, say the page name is The_Page_Name. I would like to add a known term (say, The_Reference) to Wikipedia that should redirect to The_Page_Name. They are both synonyms that overlap each other.
How to create a page reference in Wikipedia (synonym redirection)?

I believe what you are looking for is a Redirect. Information on this can be found here: http://en.wikipedia.org/wiki/Wikipedia:RedirectTo create a basic redirect manually, set #REDIRECT [[target page name  here]] as the only body text of the page. For instance, if you were  redirecting from UK to United Kingdom, this would be the entire  body of the UK page:#REDIRECT [[United Kingdom]]
