'non-administrative' originates from the prefix 'non-' meaning 'not' and the word 'administrative' from Latin 'administrativus', where 'administrare' meant 'to manage or direct'.

'administrativus' transformed into the French word 'administratif', and eventually became the modern English word 'administrative'.

Initially, 'administrative' meant 'related to management or direction', and 'non-administrative' evolved to mean 'not related to management or direction'.
