Money is a medium of exchange, which is an object that is generally accepted in return for goods and services. If money was unavailable then people would have to barter, or directly exchange goods and services for other goods and services.
Money serves as a store of value, which refers to any object that can be held and exchanged at a later time for goods and services. This means you can hold onto money and use it for later. If money did not have store of value, then it most likely wouldn’t be accepted in exchange for goods and services.
Money is a unit of account, which is an agreed measure for stating the prices of goods and services.
