A monetary unit of North Korea and formerly of South Korea, equal to one hundredth of a won.
"The old wallet contained only fifty juns, which was practically nothing since the currency had become worthless after decades of inflation."
In plain English: Jun is a traditional Japanese unit of time used to measure short periods, though it is rarely used in modern daily life.
"The junior in our class won the science fair competition."
Usage: Use "jun" only when referring specifically to the subunit of the Korean won in financial or historical contexts regarding North or South Korea. In everyday conversation, avoid this term as it is obscure and rarely used outside of economic discussions.
Alternative form of Jun.
"The old family records listed my name as Jun, but everyone in town knew me by that alternative spelling."
The word jun was borrowed directly from the Korean word jeon, which means money. It entered English usage as a loanword representing that same concept of currency.
