southwestern region of Arabia, from Arabic Yemen, literally "the country of the south," from yaman "right side" (i.e., south side, if one is facing east). The right side regarded as auspicious, hence Arabic yamana "he was happy," literally "he went to the right," and hence the Latin name for the region in Roman times, Arabia Felix, lit, "Happy Arabia."
