Abstract
The goal of this work is to look at the opposition of empirical terms – theoretical terms from a linguistic point of view, identifying attributes of the theoretical and empirical in terminology. It is proposed to be guided by the following principles.Theoricity is a graded (scaled) property. The term can be more or less theoretical, and even the minimum degree of its theoricity (provided, for example, by its definition, the understanding of which does not require special knowledge) means it is not entirely empirical. Empiricism of the term implies its perception and assimilation through any non-verbal (verbal) assimilation and explanation of it.These provisions cover terminology of various sciences and fields of knowledge, including humanities.
