'polymorphically' originates from Greek, specifically the word 'polymorphos,' where 'poly-' meant 'many' and 'morphē' meant 'form.'

'polymorphos' transformed into the English word 'polymorphic,' and eventually became the adverb 'polymorphically.'

Initially, it meant 'having many forms,' but over time it evolved into its current meaning of 'in a manner that exhibits polymorphism.'
