The lexical-semantic field is defined as a paradigmatic structure, consisting of lexical units that share a common meaning area and are in immediate opposition to each other. In recent years, many reseaces have been devoted to lexical systems from the vocabulary of different languages, with particular reference to semantic fields, sub-assemblies, suchas parenting, colors, flora and fauna, measures and weights, military grades, moral and aesthetic judgments. The results obtained have conclusively demonstrated the value of the structuralist approach to semantics and confirmed the judgments made by the first scholars of the field, such as Humboldt, Saussure and Sapir, who ergued that the vocabularies of the different languages are non-isomotphic; there are semantic distinctions made in one language and which are not made in another language; certain semantic fields may be categorized completely differently in other languages, that is each language requiresa specific form over an undifferentiated substance of the content plan. Generally speaking, it is considered that the entire lexical structure of a language is organized in semantic fields, some of them being relatively simple (such as the semantic field of color names or of kinship degrees) and others are presented as highly complex paradigmatic structures (the semantic field of character traits).
