'souvenir' originates from French, specifically the word 'souvenir,' where 'sou-' meant 'under' and 'venir' meant 'to come.'

'souvenir' changed from the Old French word 'souvenir' and eventually became the modern English word 'souvenir'.

Initially, it meant 'to remember,' but over time it evolved into its current meaning of 'a keepsake or memento.'
