'imprecisely-built' originates from the English word 'imprecise,' which is derived from the Latin word 'imprecisus,' where 'im-' meant 'not' and 'precisus' meant 'cut off or precise.'

'imprecisus' transformed into the French word 'imprécis,' and eventually became the modern English word 'imprecise,' which is combined with 'built' to form 'imprecisely-built.'

Initially, 'imprecise' meant 'not exact or accurate,' and this meaning has largely remained the same in modern usage.
