'significantly' originates from Latin, specifically the word 'significare,' where 'signum' meant 'sign' and 'facere' meant 'to make.' 'Change' originates from Old French 'changier,' which came from Latin 'cambiare,' meaning 'to exchange.'

'Significantly' evolved from the Latin 'significare' through Old French 'signifier' and Middle English 'signifien.' 'Change' evolved from Old French 'changier' to Middle English 'chaungen.'

Initially, 'significantly' meant 'to make a sign,' but over time it evolved into its current meaning of 'to a great extent.' 'Change' has largely retained its original meaning of 'to make different.'
