People from outside a civilized society, or those considered uncivilized or crude by others.
From Latin 'barbarus,' which came from Greek 'barbaros,' originally meaning 'foreign' or 'non-Greek.' The Greeks used it to mock people who didn't speak Greek, claiming their language sounded like 'bar-bar-bar' (unintelligible). Over time it shifted to mean 'uncivilized' or 'savage.'
