Having the characteristics of the backwoods; rough, unsophisticated, or rustic in manner or appearance.
From 'backwoods' plus the adjectival suffix '-y.' Emerged in 19th-century American English, often carrying somewhat pejorative but also sometimes affectionate connotations.
Interestingly, 'backwoodsy' has flipped in recent decades—what was once an insult (implying ignorance) is now sometimes claimed as a badge of authenticity, connecting to environmental awareness and distrust of overcivilization.
