'assumption-driven' originates from the combination of 'assumption' and 'driven', where 'assumption' comes from Latin 'assumptio', meaning 'a taking up', and 'driven' is the past participle of 'drive', from Old English 'drīfan'.

'Assumption' evolved from Latin 'assumptio' through Old French 'assumpcion', while 'driven' comes from Old English 'drīfan'.

Initially, 'assumption' meant 'a taking up', but over time it evolved to mean 'a supposition'. 'Driven' has largely retained its meaning of 'propelled or motivated by'.
