Gest \JEST\ , noun;
1. A notable deed or exploit
2. Archaic: A metrical romance or history
According to Etymonline.com:
The word dates back to the 1300's and comes from Old French geste ("action, exploit, romance") which derives from Latin gesta ("actions, exploits"). Gesta is the neuter plural of gestus, the past participle of gerere, which means "to carry on, wage, perform." The English word jest comes from the same lineage.
