'excursionist' originates from the Latin word 'excursio,' where 'ex-' meant 'out' and 'currere' meant 'to run.'

'excursio' transformed into the French word 'excursion,' and eventually became the modern English word 'excursionist' through Middle English.

Initially, it meant 'a running out or sally,' but over time it evolved into its current meaning of 'a person who goes on a short journey for pleasure.'
