cash

Money in the form of coins or banknotes, rather than checks, credit cards, or electronic transfers. It refers to physical money that can be immediately exchanged for goods or services. The broader concept of 'cash management' or 'cash flow' (e.g., as in the Spanish 'concepto de caja') refers to the overall handling and movement of liquid assets within a business or economy, and while 'cash' is the core element, the full concept does not have a single direct equivalent English word but is rather described by phrases like 'cash flow' or 'treasury management'.
