'meticulously' originates from Latin, specifically the word 'meticulosus,' where 'metus' meant 'fear.' 'Studied' comes from the Latin 'studium,' meaning 'zeal or dedication.'

'meticulosus' transformed into the French word 'méticuleux,' and eventually became the modern English word 'meticulous.' 'Studium' evolved into the Old French 'estudie,' leading to the modern English 'study.'

Initially, 'meticulous' meant 'full of fear,' but over time it evolved into its current meaning of 'showing great attention to detail.' 'Study' has largely retained its original meaning of 'dedication to learning.'
