'precisely-formed' originates from the Latin word 'precisus,' meaning 'cut off' or 'exact,' combined with the English word 'form,' meaning 'shape or structure.'

'precisus' transformed into the Old French word 'precis,' and eventually became the modern English word 'precise,' which is combined with 'form' to create 'precisely-formed.'

Initially, 'precisus' meant 'cut off' or 'exact,' but over time it evolved into its current meaning of 'formed with exactness and accuracy.'
