'non-representative' originates from the prefix 'non-' meaning 'not' and the word 'representative', which comes from Latin 'repraesentare', meaning 'to show or exhibit'.

'representative' evolved from the Latin 'repraesentare', through Old French 'representer', and eventually became the modern English word 'representative'.

Initially, 'representative' meant 'to show or exhibit', but over time it evolved to mean 'serving as a typical example'. The prefix 'non-' negates this meaning.
