tincture

Tincture derives from the same root as "tint" and "tinge" - the Latin verb tingere, meaning "to moisten or dip." "Tincture" specifically derives via Middle English from the Latin tinctus, the past participle of "tingere." When the word first appeared in English in the 14th century, "tincture" referred to a coloring matter or dye, but by the 17th century the word had acquired a number of additional meanings, including "a slight infusion or trace of something." "Tinge" and "shade" are two other words referring to color that can be used the same way. "Tincture" can also refer, among other things, to the colors used in a coat of arms or an herbal or medicinal solution.
