'reaccept' is formed from the prefix 're-' (from Latin 're-' meaning 'again') + the verb 'accept' (from Latin 'accipere').

'accept' originates from Latin 'accipere' (ad- 'toward' + capere 'to take'), passed into Old French as 'accepter' and into Middle English as 'accepten', eventually becoming modern English 'accept'. The modern formation 'reaccept' is a late, transparent compound using the productive English prefix 're-'.

Originally, 'accept' meant 'to receive, take', and over time it developed the sense 'to consent to receive or approve'; 'reaccept' simply adds the sense 'again' to that existing meaning.
