What is the most realistically relevant definition of money?

Money is a medium of exchange that is widely accepted in transactions for goods, services, and debts. It serves as a unit of account, a store of value, and a standard of deferred payment. Money can take various forms, such as coins, banknotes, or digital currency, and is essential for facilitating economic activities and enabling individuals to trade and conduct business efficiently.

Anything that is widely accepted as a means of payment for goods and services.

This definition is broad enough to encompass all of the different forms that money can take, from physical cash to digital currencies. It also highlights the most important function of money, which is to facilitate transactions.

Money is not just a store of value or a unit of account. It is also a medium of exchange. This means that money allows us to buy and sell goods and services without having to resort to bartering. This makes it much easier to trade, and it helps to promote economic growth.

The definition of money is not always clear-cut. There are some things that are sometimes considered to be money, but not always. For example, gift cards can be used to purchase goods and services, but they are not always considered to be money because they are not widely accepted.

Ultimately, the definition of money is determined by the people who use it. If a particular item is widely accepted as a means of payment, then it is money.
