The article covers the study of industry-specific vocabulary in Ukrainian translated lexicography of the early twentieth century (post-revolutionary era). The analysis is based on the “Moscow-Ukrainian Dictionary” (1918) written by V. Dubrovskyi. Sector-specific vocabulary in the analyzed source has its remarks as most lexicographical works have. We selected all marked units with the help of a specially created lexicographic system. The previously published article has its detailed description. The studied material thus, counts around 4 % of industry-specific words.
 According to our calculations, the most numerically predominant dictionary units are the units of both biology (including botanical, zoological and anatomical terms) and medicine.
 The most numerous nomenclature is the botanical one. To one Russian word, we can find multiple Ukrainian equivalents including various dialectal, regional, folk names, etc. Generally speaking, synonymy is a prevailing phenomenon to many fields of knowledge.
 The zoological nomenclature is quite frequent in the analyzed dictionary too. There are many names of animals (mostly non-local) that cannot be found in the Ukrainian language today. They are absent in modern lexicographical works too. Many of them even cannot be found in the dictionaries of the post-revolutionary era.
 Many little-known, colloquial, dialectal and even stylistically reduced names are can be found in the field of anatomy. Numerous names of diseases that are recorded in the “Moscow-Ukrainian Dictionary” are not part of the common medical terminology.
 Comparing to the above mentioned fields, the analyzed work presents fewer terms from the field of grammar, mineralogy, mathematics, chemistry, music, military affairs, and technology. The biggest number of words that belong to the modern Ukrainian scientific language can be found in the fields of grammar, mathematics and chemistry.
 Few single terms that were mentioned in the dictionary belong to such sciences as veterinary medicine, hunting, construction, etc.
 Consequently, the “Moscow-Ukrainian Dictionary” contains a number of industry-specific vocabulary that is not registered in the modern Ukrainian scientific language. Moreover, synonymy is considered to be a prevailing phenomenon, despite being not typically used in all industries. Largely as a result of the analysis made, the author indeed desires to choose Ukrainian terms that would be as different as possible from the Russian equivalents.
