'finely-formed' originates from the combination of 'fine' and 'formed', where 'fine' meant 'of high quality' and 'formed' meant 'shaped or structured'.

'finely-formed' evolved from the Old English word 'fīne' and 'formed', eventually becoming the modern English word 'finely-formed'.

Initially, it meant 'well-shaped or structured', and this meaning has largely remained the same in modern usage.
