Non-Terminal

A non-terminal in BNF represents a rule or pattern that can be expanded into other terminals or non-terminals.

Recursive

Recursive in BNF refers to the ability of a rule to refer to itself, creating a loop or repetition in the grammar.

Visual or graphical representations of BNF rules that help in understanding the structure of a language.
