'rapidly-done' originates from the English word 'rapidly,' which comes from the Latin word 'rapidus,' meaning 'swift' or 'quick,' and 'done,' from the Old English 'don,' meaning 'to perform or execute.'

'rapidly' evolved from the Latin 'rapidus' through Middle English, while 'done' evolved from Old English 'don.'

Initially, 'rapidly' meant 'swiftly,' and 'done' meant 'performed.' Together, they convey the idea of something completed quickly.
