'non-accumulable' originates from Latin, specifically the word 'accumulare,' where 'ad-' meant 'to' and 'cumulare' meant 'to heap up.' The prefix 'non-' is used to indicate negation.

'accumulare' transformed into the French word 'accumuler,' and eventually became the modern English word 'accumulate.' The prefix 'non-' was added to form 'non-accumulable.'

Initially, 'accumulare' meant 'to heap up,' but with the prefix 'non-,' it evolved to mean 'not capable of being accumulated.'
