Archetypes. How many are there, and what are they?
Basically, an archetype is a prototype; a model on which all others are based.
The problem is that archetypes are found in a variety of fields, e.g. psychology, literature, drama, mythology. Each field adds its own flavoring to the word. For example, Jungian psychology ramps up archetype to a universal model subconsciously shared by all of us.
Of course as authors, we're looking for character archetypes. Are there seven? Eight? Twenty-eight? Depends on which website you visit. Some base their archetypes on recurring mythic characters; some on their roles within the story.
Here are some interesting links I found. (No recommendations explicit or implied here, they're simply places I found with ideas that might jump start your own. That having been said, I did see some neat ideas :)
