'steadiness' originates from Old English, specifically the word 'stede,' where 'stede' meant 'place' or 'position.'

'stede' transformed into the Middle English word 'stedi,' and eventually became the modern English word 'steady,' from which 'steadiness' is derived.

Initially, it meant 'a place or position,' but over time it evolved into its current meaning of 'the quality of being steady or stable.'
