CASH
Cash usually refers to money in the form of liquid currency, such as banknotes or coins.
The English word cash is a borrowing
of the French caisse, itself a borrowing of the Provençal
caissa. That Provençal word is a derivative
of the Latin capsa (box, chest), most likely by way
of an unattested Vulgar Latin form *capsea; Spanish
caja and Portuguese caixa are their respective languages'
reflexes. From the original sense of a box or a chest,
the word came to refer to a sum of money such as was
or might be contained in one, and eventually to specie
or, with the elimination of metallic standards, banknotes.
In this sense, it is used in contrast to credit or
other financial instruments.
Etymology: from Sanskrit karsa, a weight of gold or silver but akin to Old Persian karsha-, a weight. a unit of value equivalent to one cash coin.
