'unquantified' originates from the prefix 'un-' meaning 'not' and the word 'quantified' from Latin 'quantificare', where 'quantus' meant 'how much' and 'facere' meant 'to make'.

'quantificare' transformed into the English word 'quantify', and with the addition of the prefix 'un-', it became 'unquantified'.

Initially, it meant 'not made into a quantity', and this meaning has largely remained the same in modern usage.
