'steady' originates from Old English, specifically the word 'stede,' where 'stede' meant 'place or position.' 'Support' originates from Latin, specifically the word 'supportare,' where 'sub-' meant 'under' and 'portare' meant 'to carry.'

'stede' transformed into the Middle English word 'stedi,' and eventually became the modern English word 'steady.' 'Supportare' transformed into the Old French word 'supporter,' and eventually became the modern English word 'support.'

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