Annotation
The notion of a context-free grammar over a free group is introduced. The transformation of any type-0 grammar to an equivalent context-free grammar over a free group is demonstrated. This approach causes an undesirable increase of the number of nonterminal symbols. Hence we introduce a method for their reduction.
