'amethystlike' originates from the word 'amethyst', which comes from the Greek word 'amethystos', meaning 'not intoxicated', as the stone was believed to prevent drunkenness.

'amethystos' transformed into the Latin word 'amethystus', and eventually became the modern English word 'amethyst'. The suffix '-like' was added to form 'amethystlike'.

Initially, 'amethyst' referred to the gemstone itself, but 'amethystlike' evolved to describe anything resembling the stone, especially in color.
