This book is about "Predicate Driven Grammar" (PDG), a new type of linguistic grammar. PDG is strongly influenced by the Sense-Text-Model and by the writings of Zellig Harris and Maurice Gross. Unlike most other grammars, PDG presupposes a language to be a relation over the Cartesian product of a set of texts and a set of meanings. A PDG assigns to each text the set of its meanings and to each meaning the set of its texts and, therefore, relates each two texts that are paraphrases, no matter if they are texts of the same or of different languages. In other words, a PDG is a theory of intralingal and interlingual paraphrasing (also known as translating). A PDG is supposed to achieve this by respecting certain fundamental properties of language: ambiguity (the property of texts to have several meanings), polymorphism (the property of meanings to have several texts), predicate-basedness and non-modularity. The term "predicate-basedness" is supposed to refer to that fact that each predicate of a natural language comes with its very own set of syntax rules. The term "non-modularity" is supposed to refer to the fact that each syntax rule of a natural-language predicate comes with its very own semantics.
