The Backus–Naur form (or Panini–Backus form) is a metasyntax used to express(ie)a formal way to describe formal languages.

it is a notion for the grammers of computer programming languages.Most textbooks for programming language theory and/or semantics document the programming language in BNF.

John Backus created the notation in order to express the grammar of ALGOL.

Peter Naur later simplified Backus's notation to minimize the character set .
