're-' originates from Latin, meaning 'again', combined with 'stage', which comes from Old French 'estage' (from Vulgar Latin *staticum), where 'stare' meant 'to stand'.

'stage' changed from Old French 'estage' and eventually became the modern English word 'stage'; the prefix 're-' was attached in English to indicate repetition, producing 're-stage'.

Initially 'stage' referred to a platform or the act of presenting something; with the prefix 're-' it came to mean 'to present or perform again' (i.e., 'stage again').
