Theory means cognitive oversight. As it is has been written, it is an «imposition–description of meaning on experience». In order to understand the empirical world, human reason uses specific mechanisms such as naming, measuring, numbering all that can be numbered, classifying, categorizing, grouping or describing by means of similes. Language follows this procedure either on a first level, e.g. by attributing substantives to objects, or on a second level, e.g. by attributing comparative, numeral (cardinal and ordinal) etc. adjectives to substantives, or, finally, on a third level, a theoretical one, that includes more abstract concepts in their appropriate grammatical forms. Several techniques known from the study of language, such as grammatical analysis (e.g. division into substantives, especially those that signify action or quality, adjectives, verbs, etc.), etymology, semantic extension or reduction, metaphor, amelioration, deterioration and transformation, mechanism of selection and deviation, levels of classification from the more concrete to the more abstract, etc. provide us with useful insights into the study of Terminology.
