A system in which a single metal is used as the only standard for currency and monetary value.
The country adopted monometallism to stabilize its economy by using only gold as its currency standard.
Monometallism is formed from "mono-" (meaning one) and "metallum" (meaning metal in Latin). The term refers to a monetary system based on a single metal, typically gold or silver, as the standard for currency.
Think of 'mono-' meaning one, and 'metallum' meaning metal — this helps you remember that monometallism refers to a system using one type of metal for currency.
