Abstract :
This correspondence discusses a restrictive structure of the customary hierarchy of formal languages attained by imposing restrictions on a set of productions and on their Iuse by means of codewords. A coded fuzzy language (CFL) is defined in order gap between formal languages and natural languages. Somte properties of CFLs and their relationships to the restrictive device are studied. A cyclic language of order n is defined to investigate properties of formal and fuzzy languages with regard to classes of recognizers.
