The article is devoted to the research of the Latin medical-veterinary clinical terminology system – one of the subsystems of general medical-veterinary terminology. The ways of formation of the Latin Sublanguage of clinical veterinary medicine are analyzed, sources of its replenishment are determined; It was discovered that most of the terms are composed using terms of Greek-Latin origin, which is a decisive trend in the development of the terminology of veterinary medicine and in our time.It is investigated that for the modern terminological word formation of clinical veterinary vocabulary all main methods are typical, by means of which the vocabulary of the veterinary doctor is replenished: semantical, syntactical, morphological. In the article a word-formation, lexical-semantic and syntactical analysis of the Latin clinical veterinary terminology was made for the first time; the main word-building models are described, the derivation processes, word-formation fortresses of the Latin clinical veterinary terms are described and the complex of methods of their word-formation are analyzed;defined the status and semantic characteristics of formants– components of the term; the lexical-semantic features of the studied terminology are revealed; attention was paid to etymology, the phenomenon of derivation and the most productive affixes and term elements in the structure of one-word clinical veterinary terms.The systematization of term elements according to thematic groups that are in a certain lexical-semantic relationship is carried out, namely: termelements, which denote the names of sciences, treatment, methods of diagnostic examination, surgical techniques; word-formation elements for the designation of organs of animals and tissues; therapeutic methods, names of pathological changes of organs and tissues; term elements that denote various physical properties, quality, color, size; word-formation elements to denote functional changes, processes, and states.The attention is paid to the morphological and syntactical structure of single, dual, and verbose clinical terms with different types of definitions. We consider one of the most important tasks of modern linguistics - not only to fix, study and analyze lexical-semantic innovation processes in terminology, but also codify the terminology system itself. Therefore, one of the priority directions of terminological work in the field of veterinary medicine at the present stage is the normalization of clinical terminology, that is, the revision of the terminology system in accordance with the conceptual basis and norms of the Latin and Ukrainian scientific languages. As the most important aspect, we consider the development of a single concept of terminology, which uses the experience and positive achievements of scientists of different generations.Provision of linguistic normative terms should take place at all levels – both conceptual and actual language – phonetic, orthoepic, spelling, lexical-semantic, word-building, morphological, syntactical.
