A observe is expounded to be primitive if it can't be represented as any strength of one other be aware. it's a famous conjecture that the set of all primitive phrases Q over a non-trivial alphabet isn't context-free: this conjecture remains to be open. during this publication, the authors care for houses of primitive phrases over a non-primitive alphabet, the language which include all primitive phrases and similar languages. in addition, a few decidable and undecidable issues of recognize to the above languages are mentioned to boot. As one other try out, a look for a non-phrase constitution grammar which generates Q is performed.
