Annotation 

This paper discusses new kind of a restriction placed on treecontrolled grammarscontextfree grammars with some roottoleaf paths in their derivation trees restricted by a control language. We introduce an npath restriction and demonstrate that if the control language is linear, there are several families of generated languages depending on the length of common part of restricted paths. Then, the paper introduces several pumping properties of these families.
