'steady' originates from Old English, specifically the word 'stede,' where 'stede' meant 'place or position.' 'Grow' originates from Old English 'grōwan,' meaning 'to flourish or increase.'

'steadily' changed from the Old English word 'stede' and eventually became the modern English word 'steady.' 'Growing' evolved from 'grōwan' to 'grow' in modern English.

Initially, 'steady' meant 'firmly placed,' but over time it evolved into its current meaning of 'consistent or continuous.' 'Grow' initially meant 'to flourish,' and this meaning has largely remained the same in modern usage.
