'managerial-supportive' is a compound word formed from 'managerial' and 'supportive'. 'Managerial' originates from 'manager', which comes from the Latin word 'manu agere', meaning 'to lead by hand'. 'Supportive' comes from 'support', which originates from the Latin word 'supportare', meaning 'to carry from below'.

'Managerial' evolved from the Latin 'manu agere' through Old French 'managier' to Middle English 'manage'. 'Supportive' evolved from Latin 'supportare' through Old French 'supporter' to Middle English 'support'.

Initially, 'managerial' meant 'to lead or direct', and 'supportive' meant 'to carry or hold up'. Over time, 'managerial-supportive' evolved to mean providing support in a managerial context.
