Types of money

The word "money" is believed to originate from a temple of Juno, on Capitoline, one of Rome's seven hills. In the ancient world Juno was often associated with money. The temple of Juno Moneta at Rome was the place where the mint of Ancient Rome was located.^[10] The name "Juno" may derive from the Etruscan goddess Uni (which means "the one", "unique", "unit", "union", "united") and "Moneta" either from the Latin word "monere" (remind, warn, or instruct) or the Greek word "moneres" (alone, unique).

In the Western world, a prevalent term for coin-money has been specie, stemming from Latin in specie, meaning 'in kind'.

In Money and the Mechanism of Exchange (1875), William Stanley Jevons famously analyzed money in terms of four functions: amedium of exchange, a common measure of value (or unit of account), a standard of value (or standard of deferred payment), and a store of value. By 1919, Jevons's four functions of money were summarized in the couplet:

Money's a matter of functions four,

A Medium, a Measure, a Standard, a Store.

This couplet would later become widely popular in macroeconomics textbooks.
