This document provides an introduction to money, covering its types, functions, and characteristics. It discusses two main types of money: commodity money, which takes the form of commodities like gold and silver; and fiat money, which derives its value by government decree rather than intrinsic value. Money serves four main functions: as a medium of exchange, a unit of account, a standard for deferred payment, and a store of value. Key characteristics that make something suitable as money include durability, portability, divisibility, uniformity, and limited supply. The document explores these concepts through examples and vocabulary terms to provide an overview of the fundamental aspects of money.
