'accurately-contoured' is a compound word formed from 'accurate' and 'contour'. 'Accurate' originates from Latin, specifically the word 'accuratus', where 'ad-' meant 'toward' and 'curare' meant 'to take care of'. 'Contour' comes from French 'contour', meaning 'outline'.

'Accurate' changed from the Latin word 'accuratus' and eventually became the modern English word 'accurate'. 'Contour' evolved from the French word 'contour' into modern English.

Initially, 'accurate' meant 'done with care', but over time it evolved into its current meaning of 'precise'. 'Contour' has largely retained its original meaning of 'outline'.
