'steady' originates from Old English, specifically the word 'stede,' where 'stede' meant 'place or position.' 'Regular' originates from Latin, specifically the word 'regularis,' where 'regula' meant 'rule.'

'steady' changed from Old English 'stede' to Middle English 'stedi,' and eventually became the modern English word 'steady.' 'Regular' transformed from Latin 'regularis' to Old French 'reguler,' and eventually became the modern English word 'regular.'

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