'steady' originates from Old English, specifically the word 'stede,' where 'stede' meant 'place or position.' 'Focus' originates from Latin, specifically the word 'focus,' where 'focus' meant 'hearth or fireplace.'

'steady' changed from Old English word 'stede' and eventually became the modern English word 'steady.' 'Focus' transformed from Latin 'focus' to the modern English 'focus' through Middle French 'foucs.'

Initially, 'steady' meant 'firmly placed,' but over time it evolved into its current meaning of 'consistent and unwavering.' 'Focus' initially meant 'hearth,' but evolved to mean 'center of activity or attention.'
