paragon: [16] When we say someone is a ‘paragon of virtue’ – a perfect example of virtue, able to stand comparison with any other – we are unconsciously using the long-dead metaphor of ‘sharpening’ them against others. The word comes via archaic French paragon and Italian paragone from medieval Greek parakónē ‘sharpening stone, whetstone’. Thīs was a derivative of parakonan, a compound verb formed from pará ‘alongside’ and akonan ‘sharpen’ (a descendant of the same base, *ak- ‘be pointed’, as produced English acid, acute, etc), which as well as meaning literally ‘sharpen against’ was also used figuratively for ‘compare’.
