'administrative-supportive' originates from the combination of 'administrative' and 'supportive', where 'administrative' is derived from Latin 'administrativus', meaning 'pertaining to management', and 'supportive' from Latin 'supportare', meaning 'to carry or bear'.

'administrative' changed from the Latin word 'administrativus' and 'supportive' from 'supportare', eventually forming the modern English compound word 'administrative-supportive'.

Initially, 'administrative' meant 'pertaining to management', and 'supportive' meant 'to carry or bear'. Together, they evolved to mean 'providing support in an administrative capacity'.
