Where it comes from
From earlier gugaw, gygaw, from Middle English givegove (“gewgaw, trifle”), a reduplication of Middle English give, geove (“gift”), from Old English giefu, geofu, geafu (“gift”), from Proto-Germanic *gebō (“gift”). Compare Icelandic gyligjöf (“showy gifts, gewgaw”). More at give.
