From Middle English japen (“to deceive, play tricks on; act foolishly, joke; have sex with”), of uncertain origin, but perhaps combining Old French japer (“to bark, howl, scream; chatter, gossip”) with gaber (“to mock, deride”). See also gab, Old Occitan japar, jaupar (“to bark, yelp, yap”), related to Old Saxon galpōn (“to cry loudly, make a noise, brag”) (Low German galpen (“to bark, howl, scream”)), Middle High German gelpfen (“to scream, bark, boast, proclaim”), Old Norse gjálpa (“to yelp”) (dialectal Swedish galpa (“to cry, screech”)). More at yelp, yawp, yap.
