banknote

This term refers specifically to the physical piece of paper representing a currency value. It carries a formal connotation, often used in official, legal, or financial contexts to distinguish the physical medium from the abstract concept of money or digital balances. In some dialects, particularly British English, it is the standard term for paper currency, whereas American English more frequently uses the term bill. It is a countable noun, meaning it can be pluralized to banknotes when referring to multiple pieces of currency.
