This work provides a brief overview of the basic relationships of meaning and structure of a language. The overview is followed by a more detailed analysis and practical application of the semantic relationships from the lowest level propositions through the highest level units of the text. A significant portion of the work addresses the semantic relations and roles of the communication units. The theory described in The Semantic Structure of Written Communication is applied in the books in the Semantic Structure Analyses Series. Each book has a systematic presentation, via a standard format and a tightly controlled discourse analysis of the Semantic Structure of the Greek text of the New Testament. The books in the Semantic Structure Analyses Series are designed to be used as a special kind of commentary to help translators find the precise meaning of the Source Language text. The SSA books are especially useful at points where regular New Testament commentaries are in disagreement or do not address themselves to the questions that translators are obliged to answer in the process of their work. In its format, an SSA includes a display of the semantic content and structure of each paragraph and each grouping of paragraphs in the text, in a form somewhat resembling a tree diagram. Also included are notes and comments justifying the analytical and exegetical decisions presented.
