'imprecisely-shaped' originates from the Latin word 'imprecisus,' where 'im-' meant 'not' and 'precisus' meant 'cut off or defined.'

'imprecisus' transformed into the French word 'imprécis,' and eventually became the modern English word 'imprecise' through Middle English.

Initially, it meant 'not clearly defined,' and this meaning has largely remained the same in modern usage.
