Auctions are a venerable selling institution, in use since the time of Herodotus. The word comes from the Latin auctus, meaning to increase. An obscure term for auction, one guaranteed to impress friends and neighbors, is the Latin word subhastare. It is the conjunction of sub, meaning "under," and hasta, meaning "spear." After a military victory, a Roman soldier would plant his spear in the ground to mark the location of his spoils. Later, he would put these goods up for sale by auction.
¹The highest bidder was called the emptor, whence the term caveat emptor.
