'versed' originates from Latin, specifically the word 'versatus,' where 'versare' meant 'to turn or to be engaged in.'

'versatus' transformed into the Old French word 'versé,' and eventually became the modern English word 'versed' through Middle English.

Initially, it meant 'to be engaged in or occupied with,' but over time it evolved into its current meaning of 'having knowledge or skill in a particular area.'
