'experience-based' originates from the combination of 'experience' and 'based', where 'experience' comes from Latin 'experientia', meaning 'knowledge gained by repeated trials', and 'based' comes from Old French 'basse', meaning 'foundation'.

'experience' evolved from the Latin 'experientia' through Old French 'experience', and 'based' evolved from Old French 'basse' to the modern English 'base'.

Initially, 'experience' meant 'knowledge gained by repeated trials', and 'based' meant 'foundation'. Together, they evolved to mean 'derived from personal experience'.
