'classifiable' originates from the verb 'classify,' which comes from the Latin word 'classificare,' where 'classis' meant 'class' and 'facere' meant 'to make.'

'classificare' transformed into the French word 'classifier,' and eventually became the modern English word 'classify,' from which 'classifiable' is derived.

Initially, it meant 'to arrange in classes,' and this meaning has largely remained the same in modern usage.
