'meticulously' originates from Latin, specifically the word 'meticulosus,' where 'metus' meant 'fear.' 'Performed' comes from Old French 'parfournir,' meaning 'to complete.'

'Meticulosus' transformed into the English word 'meticulous,' and 'parfournir' became 'perform' in modern English.

Initially, 'meticulous' meant 'full of fear,' but over time it evolved into its current meaning of 'showing great attention to detail.'
