What is the name for that type of word that modifies a noun or verb with an ending to denote someone who is associated with the word stem?
I'm thinking of words like:
- engineer, farmer (ending = "eer", "er")
- Ohioan (ending = "an")
- Michigander, New Yorker (ending = "der", "er")
- Seattleite (ending = "ite", "lite")
Particularly, I'm interested in what you call it when you coin a new such word by adding an ending. For example, Disney's "imagineer". And I'd love to see a compendium of such words that have this property.
