Etymology: "Colourants" is the plural of "colourant", a noun for any substance that adds tint, such as a dye or pigment. It is formed from "colour" plus the suffix "-ant", which in English marks a thing or agent that performs an action, so a colourant is literally something that colours. The suffix descends through Old French "-ant" and Latin "-ans" and "-ānsa" from a Proto-Indo-European ending, and it reached English as the same suffix that appears in words like "servant" and "pollutant". The base word "colour" entered English through Old French "colour" from Latin "color", and the suffix was simply attached to it. Because the formation is a plain combination of two familiar parts, the word's history is transparent: it names whatever does the colouring, and the plural simply counts several such substances at once.
