gannet: [OE] The gannet used to be known dialectally as the solan goose (solan was a compound formed in the 15th century from Old Norse súla ‘gannet’ and önd ‘duck’), and in fact the name gannet too reveals a perceived similarity between the gannet and the goose. For it comes ultimately from a prehistoric Germanic *ganitaz or *ganoton, a word formed from the same base as produced English gander [10]. => gander[gannet etymology, gannet origin, 英语词源]
