'external-focused' originates from the combination of 'external,' derived from Latin 'externus,' meaning 'outside,' and 'focused,' from Latin 'focus,' meaning 'hearth' or 'center.'

'external' changed from the Latin word 'externus' and eventually became the modern English word 'external.' 'Focused' evolved from the Latin 'focus' through Middle English 'focussed.'

Initially, 'external' meant 'outside' or 'outer,' and 'focused' meant 'centered.' Over time, 'external-focused' evolved to mean concentrating on external factors.
