'rapidly-formed' originates from the combination of 'rapidly' and 'formed', where 'rapidly' is derived from the Latin word 'rapidus', meaning 'swift', and 'formed' is from the Old English 'formian', meaning 'to shape'.

'rapidly' evolved from the Latin 'rapidus' through Old French 'rapide', and 'formed' from Old English 'formian'.

Initially, 'rapidly' meant 'swiftly', and 'formed' meant 'to shape'. Together, they convey the idea of something shaped quickly.
