What does currency mean?
Currency refers to a system of money in general use within a country or region, typically comprising coins and banknotes issued by an authorised authority such as a central bank. The pound sterling, the US dollar, and the euro are all examples of currencies, and most nations maintain exactly one, though some share one with neighbours or accept several alongside their own. Beyond its financial meaning, currency also carries a figurative sense denoting general acceptance or prevalence: an idea that 'gains currency' spreads widely and comes to be believed or discussed. This second sense derives from the same underlying notion as the first — something flowing or circulating through society, much like water in a stream. In everyday speech the word is neutral and practical, appearing constantly in contexts involving travel, exchange rates, banking, and international trade, where phrases like 'foreign currency' and 'currency exchange' are routine. Its dual character — both a concrete economic object and a metaphor for social circulation — makes it a notably versatile term in English.
A system of money in general use in a particular country, consisting of coins and banknotes; more broadly, anything that is widely accepted as a medium of exchange.
"The yen is the third most traded currency in the world."
When referring to a kind of money, the noun functions as uncountable ('foreign currency'); when counting distinct systems of money, it is countable ('the two currencies').
The quality or state of being generally accepted, prevalent, or in circulation at a given time.
"The theory gained currency in the late nineteenth century."
Often used with verbs such as 'gain', 'acquire', or 'lose'. Slightly formal register.
Used when referring to multiple distinct systems of money, e.g. those of different countries.
"The report compared inflation rates across several major currencies."
The word 'currency' literally means 'the quality of flowing' — money was named after a river metaphor, because coin was meant to circulate through society like water through a channel.

Etymology of currency
Currency derives from the Latin verb currere, meaning 'to run' or 'to flow', via the medieval Latin term currentia, referring to something in circulation. It entered English in the mid-17th century, initially describing the condition of flowing or circulating generally, and soon came to apply specifically to money in circulation. It is thus a close relative of words such as current, concur, and occur, all of which trace back to the same Latin root.
How currency is actually used
Both senses are standard in British and American English. The figurative sense ('to gain currency') is somewhat formal but common in journalism and academic writing. The word is uncountable when referring to a type of money ('foreign currency') but countable when referring to individual currencies ('several currencies are accepted here').
