'tincture' originates from Latin, specifically the word 'tinctura,' where 'tingere' meant 'to dye or color.'

'tinctura' transformed into the Old French word 'tincture,' and eventually became the modern English word 'tincture' through Middle English.

Initially, it meant 'a dye or coloring,' but over time it evolved into its current meaning of 'a medicinal solution or a slight trace.'
