gold-colored chemical dye
Etymology
'aurin' originates from Latin, specifically the word 'aurum', where 'aur-' meant 'gold'; the modern form uses the chemical suffix '-in' commonly applied to organic substances.
'aurin' developed as a chemical name in modern European languages (notably German and English) in the 19th century, formed by combining the Latin root 'aur-' (from 'aurum') with the organic compound suffix '-in', eventually stabilizing as the English term 'aurin'.
Initially the name highlighted a 'gold' or yellow/golden color association, but over time it came to denote the specific chemical dye now called aurin (historically rosolic acid).
