Cash

Cash is money in the tangible form of currency, such as banknotes and coins, that is used in economic transactions.

Cash is a kind of asset in bookkeeping and financial accounting that consists of currency or currency equivalents that may be accessed immediately or almost immediately after being acquired (as in the case of money market accounts). When it comes to cash, it is either used as a payment reserve in the event of a structural or accidental negative cash flow, or it is used to prevent a downturn in the financial markets.

It was initially intended to imply "money box," but it eventually evolved to mean "money" as well as a secondary meaning. In the 18th century, this secondary meaning supplanted the primary meaning. 'Cash' comes from the Middle French caisse (money chest), which comes from the Old Italian cassa, which comes from the Latin capsa (money) ("box").

One further possible derivation for the term "cash" is the Portuguese word caixa, which is derived from the Tamil word kcu (pronounced as kcu), which refers to a tiny copper coin made of gold or silver that was formerly common.
