In formal language theory, a context-free grammar is in Greibach normal form (GNF) if the right-hand sides of all production rules start with a terminal symbol, optionally followed by some variables. A non-strict form allows one exception to this format restriction for allowing the empty word (epsilon, ε) to be a member of the described language. The normal form was established by Sheila Greibach and it bears her name. http://cmsc-28000.cs.uchicago.edu/2024-spring/Lectures/15/ WebGreibach Normal Form (GNF) GNF stands for Greibach normal form.

WebGreibach normal form (GNF). 4 Chomsky Normal Form (CNF) A context free grammar, G is in Chomsky Normal Form, if every production is of the form, A → a, A → BC, S → ε; for this production, S is the start symbol. Thus the RHS of a production can be a single terminal, or two non-terminals. Also it can be ε, if LHS is the start symbol.
