NooJ grammars for Italian transformational analysis

As known, Transformational Grammar(TG)focuses on bidirectional relationshipsbetween sentences sharing the same lexical material, in some cases also thesamemeaning, but always differing in terms of formal structure and word distribution. We represent such relationships with the symbol “=” (equal to). For instance,we can connecta declarative sentence to its negative and/or passive forms.Similarly, we can connectcomplex sentences to therespectivesimple sentences,which make them up, such as sentences with reciprocal verbs and collective subjects,obtained through the coordination oftwo simple sentences.According to Maurice Gross[1] and Max Silberztein [2,3], examples of possible transformations arethose going from declarative sentences to Interrogatives, Pronominalization, Juxtapositions, or other processesproducing theso-called Mirror Transformations. In addition, two or more transformations can operate simultaneously on a declarative sentence.
