BNF notation consists of three pieces: Terminals, such as "x" , are strings of characters that must exactly match characters in the input. Nonterminals (or symbols for short), such as lettera , represent sets of strings. ... Rules, such as lettera ::= "a" or word ::= letter word , define how nonterminals and strings relate.
