The word "decolouring" is a derived form of the verb "decolour", which refers to the act of removing or reducing the color of something. The etymology of "decolour" can be traced back to the Latin word "decolorare", which combines the prefix "de-" (indicating negation or reversal) and the root word "color" (meaning color). Therefore, "decolour" can be interpreted as "to remove color" or "to make colorless". The addition of the suffix "-ing" transforms the verb into a present participle, resulting in "decolouring", which means the act of decolouration.
