By mastering the language, we master the knowledge of the world, because language is the "house of the spirit" with "hearth" being thought. By mastering thought, we acquire individual and historical consciousness, the most fundamental step for our presence within the historical continuity and consequence of our actions, the synthesis of everything that exists around us. Then, man is understood as an existence, as a spiritual and moral entity. This means that every person must participate in a continuous "dialectical game" of concepts and thoughts, terms and concerns. This is the purpose that the present Dictionary aspires to satisfy, with the etymological, semantic, synonymous, antonymous, verbal, adjectival, synthetic, adverbial, semantic approach of each concept, a starting point for the Expression-Exposition of middle school students.
