'technically' originates from 'technical,' which comes from the Greek word 'technikos,' meaning 'of art or skill.' 'Skilled' comes from the Old Norse word 'skilja,' meaning 'to discern or separate.'

'Technically' evolved from the Greek 'technikos' through Latin 'technicus' and Old French 'technique.' 'Skilled' evolved from Old Norse 'skilja' to Middle English 'skil.'

Initially, 'technically' meant 'pertaining to art or skill,' and 'skilled' meant 'able to discern.' Over time, they combined to describe someone proficient in technical areas.
