What is a reserved word?

A reserved Word, also known as a keyWord, is a term in programming languages that has a predefined meaning and cannot be used for any other purpose, such as naming variables or functions. These Words are integral to the syntax and structure of the language, enabling it to interpret specific commands and controls. Examples include Words like "if," "else," "while," and "return" in languages like Python and Java. Using reserved Words incorrectly can lead to syntax errors in the code.
