'identifier' originates from the Latin word 'identificare,' where 'ident-' meant 'same' and 'facere' meant 'to make.'

'identificare' transformed into the French word 'identifier,' and eventually became the modern English word 'identifier' through Middle English.

Initially, it meant 'to make the same,' but over time it evolved into its current meaning of 'a name or symbol that identifies something or someone.'
