Syntactics deals with the way signs are put together to make "sign compounds"phrases, sentences, ideas, and ideals. The word "grammar" fits into this context.
Semantics29 deals with signs in two ways:
1. Semantics deals with what signs are intended to signify. The word "purpose" is appropriate here. This area of purpose is covered in Morris's account of the four uses of language.
2. Semantics deals, also, with the way, the manner in which signs signify. This area of semantics is covered in Morris's account of the four modes of signifying. For each use, there is a corresponding mode.
Pragmatics deals with the uses and the effects of signs in a behavior situation.
Syntactics, semantics, and pragmatics are the three major divisions of semiotic. But each one of these divisions, and, hence, semiotic as a whole, may be studied, again, on three different levels: pure, descriptive, and applied.
Pure semiotic establishes the language by which to investigate signs and sign behavior, thus to formulate a science of signs. When the terminology which explicates the four uses and the four corresponding modes is presented in this Part, the terminology will derive from Morris's work in the area of pure semiotic. The field theory of communication presented in Part Five is erected on this scientific base.
Descriptive semiotic studies actual signs. Such study rests, of course, upon the use of specialized terms established in the area of pure semiotic. When, for example,
29 In The Open Self, Morris expands the scope of the term "semantics."
Here he states (pp. 52-55) that he abandons the term "semiotic'* to the specialists and embraces the term ^'semantics** for a "warmer" account of the science of signs.
