'commemorate' originates from Latin, specifically the word 'commemoratus', where 'com-' meant 'together' and 'memorare' meant 'to remind'.

'commemoratus' transformed into the French word 'commémorer', and eventually became the modern English word 'commemorate' through Middle English.

Initially, it meant 'to remind together', but over time it evolved into its current meaning of 'to honor the memory of someone or something'.
