'skill-focused' originates from the combination of 'skill' and 'focus,' where 'skill' refers to the ability to do something well and 'focus' means concentrated attention.

'Skill' and 'focus' have been used in English since the Middle Ages, with 'skill' deriving from Old Norse 'skil' and 'focus' from Latin 'focus,' meaning 'hearth' or 'fireplace.'

Initially, 'focus' meant 'hearth,' but over time it evolved to mean 'center of activity or interest,' which is how it is used in 'skill-focused.'
