jolly Look up jolly at Dictionary.com
c.1300, from O.Fr. jolif "festive, merry, amorous, pretty" of uncertain origin (cf. It. giulivo "merry, pleasant"), perhaps a Gmc. loan-word from a source akin to O.N. jol "a winter feast" (see yule), or from L. gaudere "to rejoice." Jollification "merrymaking" is from 1809; shortened form jolly led to phrase get (one's) jollies "have fun" (1957). A jolly boat (1727) is probably from Dan. jolle (17c.) or Du. jol (1680s), both related to yawl (q.v.); or it may be from M.E. jolywat (late 15c.) "a ship's small boat," of unknown origin.
