'non-distributable' originates from the prefix 'non-' meaning 'not' and the word 'distributable' from Latin 'distribuere', where 'dis-' meant 'apart' and 'tribuere' meant 'to assign'.

'distribuere' transformed into the English word 'distribute', and eventually became 'distributable' with the addition of the suffix '-able', leading to the modern term 'non-distributable' with the prefix 'non-'.

Initially, 'distributable' meant 'capable of being distributed', and with the prefix 'non-', it evolved to mean 'not capable of being distributed'.
