'quickly-rebuilt' is a compound word formed from 'quickly' and 'rebuilt'. 'Quickly' originates from Old English 'cwic', meaning 'alive' or 'lively', and 'rebuilt' is the past participle of 'rebuild', which comes from Middle English 'rebuilden', combining 're-' meaning 'again' and 'build' from Old English 'byldan'.

'quickly' evolved from Old English 'cwic' to Middle English 'quik', and eventually to the modern English 'quickly'. 'Rebuilt' evolved from Middle English 'rebuilden' to the modern English 'rebuilt'.

Initially, 'quickly' meant 'alive' or 'lively', but over time it evolved to mean 'in a short time'. 'Rebuilt' has maintained its meaning of 'constructed again'.
