'specificity' originates from the Latin word 'specificus,' where 'species' meant 'kind or type' and '-ficus' meant 'making or doing.'

'specificus' transformed into the French word 'spécificité,' and eventually became the modern English word 'specificity.'

Initially, it meant 'pertaining to a particular kind or type,' but over time it evolved into its current meaning of 'the quality of being specific or particular.'
