The pound sign (£) is a symbol used to represent the currency of several countries, most notably the United Kingdom. It originates from the Latin word "libra," which means pound. The sign is often used in financial contexts to denote amounts of money, such as £10, indicating ten pounds. In addition to the British pound, the pound sign is also used for other currencies, such as the Egyptian pound and the Sudanese pound. Each of these currencies has its own value and exchange rate, but they share the common symbol of £ to signify their monetary units.
