rural (adj.)

early 15c., from Old French rural (14c.), from Latin ruralis "of the countryside," from rus (genitive ruris) "open land, country," from PIE *reue- (1) "to open; space" (see room (n.)).

In early examples, there is usually little or no difference between the meanings of rural and rustic, but in later use the tendency is to employ rural when the idea of locality (country scenes, etc.) is prominent, and rustic when there is a suggestion of the more primitive qualities or manners naturally attaching to country life.
