'restage' originates from the Latin prefix 're-' meaning 'again' combined with 'stage', which comes via Old French 'estage' meaning 'a stage, stopping place, or position'.

'restage' was formed in modern English by attaching the prefix 're-' to 'stage' (Old French 'estage'); the theatrical sense of 'stage' developed through Middle English into the modern sense, and 'restage' acquired the specific meaning 'to stage again'.

Initially, 'stage' referred to a place, position, or a phase; over time the theatrical sense (a performance platform and the act of presenting) became primary, and 'restage' came to mean 'to stage again' or 'present again'.
