ἀριστερός

Etymology
Apparently from, though the left direction has negative connotations in many cultures and languages, including Greece. According to Chantraine, the suffix -τερος serves to differentiate and create a euphemistic contrast with ἄριστος; an unusual formation. The latter is taken to indicate on the right side in this case, the left side being its literal and metaphorical opposite.
