Origin unknown. Perhaps from Old English gǣgan (“to go, walk, pass by”), as in forgǣgan (“to transgress, trespass, prevaricate, pass by, neglect, omit”), ofergǣgan (“to transgress”), or from Old Norse geiga (“to deviate to the side, go the wrong way, rove at random”), both from Proto-Germanic *gaigijaną, *gīganą (“to move”), from Proto-Indo-European *gʰeyǵʰ-, *gʰeygʰ- (“to gape, protrude”), from Proto-Indo-European *ǵʰēy(w)-, *ǵʰyāw- (“to yawn, gape”). Cognate with Old Frisian gēia (“to overstep, exceed”), Norwegian dialectal geige (“to sway back and forth”), Middle High German gīgen (“to play the violin”), Old English gǣnan (“to gape”). More at jig.
