[PW] I've lost a word and a Wikipedia page....

[Phalbe Henriksen]

Folks,

I've "lost" a Wikipedia page! I didn't realize that I.E.'s "history" 
doesn't save individual Wikipedia pages. :(

The page is about how names of countries, states, cities, areas in 
general, and cultures are changed to describe the people from them, 
e.g. Washington/Washingtonian, Liverpool/Liverpudlian, New York/New Yorker.

Does anyone recognize this or know the word that describes this?

Thanks.

so forth and so on
