Other etymologies that have been postulated for the ancient name 'Africa':

the Latin word aprica, meaning "sunny";
the Greek word aphrike, meaning "without cold." This was proposed by historian Leo Africanus (1488-1554), who suggested the Greek word phrike (f????, meaning "cold and horror"), combined with the privative prefix "a-", thus indicating a land free of cold and horror.
