'accurately-supplied' originates from the combination of 'accurate' and 'supply', where 'accurate' meant 'correct' and 'supply' meant 'to provide'.

'accurate' changed from the Latin word 'accuratus' and 'supply' from the Latin word 'supplere', eventually forming the modern English term 'accurately-supplied'.

Initially, 'accurate' meant 'done with care' and 'supply' meant 'to fill up', but over time it evolved into its current meaning of 'provided with precision'.
