'class-based' originates from the English word 'class,' which comes from the Latin word 'classis,' meaning 'a division or group,' and 'based,' which is derived from the Old French 'baser,' meaning 'to build or establish.'

'classis' transformed into the Old French 'classe,' and eventually became the modern English word 'class.' 'Baser' evolved into the modern English 'base.'

Initially, 'class' meant 'a division or group,' and 'base' meant 'to build or establish.' Over time, 'class-based' evolved to mean 'relating to a system of classification based on classes.'
