'persistent' originates from Latin, specifically the word 'persistens,' where 'per-' meant 'through' and 'sistere' meant 'to stand.'

'persistens' transformed into the French word 'persister,' and eventually became the modern English word 'persistent' through Middle English.

Initially, it meant 'to stand through,' but over time it evolved into its current meaning of 'continuing firmly or obstinately.'
