'executive-supportive' is a compound word formed from 'executive' and 'supportive'. 'Executive' originates from Latin, specifically the word 'executivus', where 'ex-' meant 'out' and 'sequi' meant 'to follow'. 'Supportive' comes from Latin 'supportare', where 'sub-' meant 'under' and 'portare' meant 'to carry'.

'Executive' evolved from the Latin 'executivus' through Old French 'executif', and 'supportive' evolved from Latin 'supportare' through Old French 'supporter'.

Initially, 'executive' meant 'to carry out or perform', and 'supportive' meant 'to carry from beneath'. Over time, 'executive-supportive' evolved to mean providing assistance in an executive capacity.
