'externally-driven' originates from the combination of 'external' and 'drive', where 'external' comes from Latin 'externus' meaning 'outside', and 'drive' from Old English 'drīfan' meaning 'to force to move'.

'externus' transformed into the Middle English word 'extern', and 'drīfan' evolved into the modern English 'drive', eventually forming the compound adjective 'externally-driven'.

Initially, 'external' meant 'outside', and 'drive' meant 'to force to move'. Together, they evolved to mean 'influenced by outside forces'.
