A mistake! I think you meant "derivatives".<br><br>A derivative is a word or phrase that is derived from another word or phrase. In linguistics, a derivative is a new word that is formed by adding a prefix, suffix, or infix to an existing word or several words. For example, "unhappy" is a derivative of "happy", or "smiling" is a derivative of "smile". In finance, a derivative is a financial instrument that has a value that is derived from the value of an underlying asset, such as a stock or a commodity.
