'suddenly-rebuilt' originates from the combination of 'suddenly' and 'rebuilt'. 'Suddenly' comes from Middle English 'sodein', from Old French 'soudain', from Latin 'subitaneus', meaning 'unexpected'. 'Rebuilt' is the past participle of 'rebuild', which comes from Middle English 'rebuilden', from 're-' meaning 'again' and 'builden' meaning 'to construct'.

'Suddenly' evolved from the Old French 'soudain', while 'rebuilt' transformed from the Middle English 'rebuilden'. Together, they form the modern English compound adjective 'suddenly-rebuilt'.

Initially, 'suddenly' meant 'unexpectedly', and 'rebuilt' meant 'constructed again'. The compound 'suddenly-rebuilt' retains these meanings, emphasizing the rapidity of reconstruction.
