'amaranth' originates from Greek, specifically the word 'amarantos,' where 'a-' meant 'not' and 'marantos' meant 'fading.'

'amarantos' transformed into the Latin word 'amaranthus,' and eventually became the modern English word 'amaranth.'

Initially, it meant 'unfading flower,' but over time it evolved into its current meaning of a plant or color.
