'community-based' originates from the word 'community,' which comes from Latin 'communitas,' meaning 'a group of people living together,' and 'based,' from Old French 'bastir,' meaning 'to build.'

'community' evolved from Latin 'communitas' to Old French 'comunité,' and eventually became the modern English word 'community.' 'Based' transformed from Old French 'bastir' to Middle English 'basten,' and eventually became 'based.'

Initially, 'community' meant 'a group of people living together,' and 'based' meant 'to build.' Over time, 'community-based' evolved to mean 'organized by or relating to a community.'
