're-erect' originates from Modern English, specifically the formation combining the prefix 're-' (from Latin 're-') meaning 'again' and 'erect' (from Latin 'erectus' / 'erigere') meaning 'to raise' or 'upright'.

're-erect' developed by adding the productive English prefix 're-' to the word 'erect'. 'Erect' itself entered English via Old French (cf. 'erecter') and Middle English from Latin 'erigere'/'erectus', and the combination produced the modern English 're-erect'.

Initially, Latin 'erigere' meant 'to raise' and 'erectus' 'upright'; over time English 'erect' kept the sense 'set upright' and the prefixed form 're-erect' came to mean 'to set upright again' or 'to rebuild/restore'.
