Things that take great strength — like throwing a boulder or finishing math homework — are sometimes called herculean in honor of the Greek god Hercules.

Just like Thursday comes from the Scandinavian god Thor, the god Hercules gave us this word. Herculean was first used to describe Hercules himself, and later applied to anyone or anything who showed similar strength. Herculean can be used in several ways. You can make a herculean effort to accomplish a herculean task. Any job that is a piece of cake — an easy job that that anyone could do — is totally non-herculean. Save this word for jobs that really deserve the label.
