'meticulously' originates from Latin, specifically the word 'meticulosus,' where 'metus' meant 'fear.' 'Prepared' comes from Latin 'praeparare,' where 'prae-' meant 'before' and 'parare' meant 'make ready.'

'Meticulosus' transformed into the French word 'méticuleux,' and eventually became the modern English word 'meticulous.' 'Praeparare' evolved into the Old French 'preparer,' and eventually became the modern English word 'prepare.'

Initially, 'meticulous' meant 'fearful,' but over time it evolved into its current meaning of 'showing great attention to detail.' 'Prepare' has largely retained its original meaning of 'make ready.'
