A novel which is the product of its fidelity to a particular geographical section, accurately representing its habits, speech, manners, history, folklore, or beliefs.  In one sense, the test of "regionalism" is that the action and personages cannot be moved, without major loss or distortion, to any other geographical setting.

A novel emphasizing the setting, speech, and social structure and customs of a particular locality, not merely as local color, but as important conditions affecting the temperament of the characters and their ways of thinking, feeling, and interacting.
