'tribesman' originates from the word 'tribe,' which comes from Latin 'tribus,' meaning 'a division of the Roman people.'

'tribus' transformed into the Old French word 'tribu,' and eventually became the modern English word 'tribe,' from which 'tribesman' is derived.

Initially, it meant 'a division of people,' but over time it evolved into its current meaning of 'a member of a tribe.'
