//What happens when a perfectly innocuous phrase takes on a more sinister meaning over time?
Case in point, the expression "to call a spade a spade." For almost half a millennium, the phrase has served as a demand to "tell it like it is." It is only in the past century that the phrase began to acquire a negative, racial overtone.
Historians trace the origins of the expression to the Greek phrase "to call a fig a fig and a trough a trough." Exactly who was the first author of "to call a trough a trough" is lost to history. Some attribute it to Aristophanes, while others attribute it to the playwright Menander.//
