'unspecific' originates from the prefix 'un-' meaning 'not' and the word 'specific' from Latin 'specificus', where 'species' meant 'kind' or 'form'.

'specificus' transformed into the English word 'specific', and with the addition of the prefix 'un-', it became 'unspecific'.

Initially, it meant 'not of a particular kind', and this meaning has largely remained the same in modern usage.
