'pre-prepared' originates from the prefix 'pre-' meaning 'before' and the word 'prepare' from Latin 'praeparare', where 'prae-' meant 'before' and 'parare' meant 'to make ready'.

'prepare' changed from the Latin word 'praeparare' and eventually became the modern English word 'prepare'.

Initially, it meant 'to make ready beforehand', and this meaning has largely remained the same in modern usage.
