Hogmanay is the Scottish name for new year celebrations.
It is not known exactly where the word comes from, although it is believed to come from the French word 'hoginane' meaning 'gala day'.
It is thought to have first been used widely following Mary, Queen of Scots' return to Scotland from France in 1561.
Dr Donna Heddle, an expert from the University of the Highlands and Islands, explained: "The name could also come from the Anglo-Saxon 'haleg monath' meaning 'holy month'."
Some say it could come from the Scandinavian 'hoggo-nott' meaning 'yule'.
But Dr Heddle says: "The most likely source seems to be French. In Normandy, presents given at Hogmanay were 'hoguignetes'."
