Hi
Ur question arose my curosity. Searched and got this about your query -

The Backus–Naur form (also known as BNF, the Backus–Naur formalism, Backus normal form, or Panini–Backus Form) is a metasyntax used to express context-free grammars: that is, a formal way to describe formal languages.

BNF is widely used as a notation for the grammars of computer programming languages, instruction sets and communication protocols, as well as a notation for representing parts of natural language grammars (for example, meter in Venpa poetry.) Most textbooks for programming language theory and/or semantics document the programming language in BNF.
