It was a derogatory way of calling the slave in the 19th century, which was later left to his descendants of African origin. Originally it was the Castilianization of the Quechua name for the hairy beetle, a black shell that pushed or loaded clay balls or excrement to make its nest (and it seemed that it was doing heavy work, like slaves). It is composed of the voices aka ( "poop") tankay ( "push" ) . It is also the name given to an old, ramshackle cargo cart; definition that today can be extended to any type of vehicle in bad conditions.
