The article describes the formation of lexical-word-forming types of null suffix derivatives to denote the names of living nature in the Ukrainian language of the XI – early XXI centuries. Derivatives that described are the deverbatives and deadjectives of masculine, feminine, rarely neutral gender, which name the names of persons, animals, plants. Only those nouns that have preserved structural and semantic correspondence with the creative bases at the time of their fixation in the texts of written memoranda of the Ukrainian language are involved in the analysis of linguistic facts. In the group of deverbatives of the masculine gender in the most ancient monuments many names of persons-performers of action by permanent or temporary occupation or by profession are documented: пророкъ ‘preacher’, посълъ, тълкъ ‘translator, interpreter’, сторожъ, отрокъ, вож, наставъ ‘mentor, teacher’, приставъ, ‘bailiff, a person intended to protect or accompany someone’, etc. No innovations with this semantics have been found in the written monuments of these centuries, they are recorded later mostly in dialects: виж ‘witness’ ворож ‘fortune teller’, бай, ‘storyteller’. Feminine names are recorded infrequently, because such formations with -a have long acquired the meaning of the common gender.Among the names of persons with a general word-forming meaning ‘carrier of a procedural sign’, meaning external or internal signs of a person (behavior, views, social status, etc.), derivatives have long being documented: лъжь (ложь) (lies) ‘deceiver’, спасъ ‘savior’; заступъ ‘defender’; изворогъ ‘unfortunate’, etc. Feminine nouns are documented much later: дура, розпакла, кудра ‘kucheryva zhyna’ (curly hair woman), поволока ‘prostitute’, etc. This lexical-word-forming type of nouns is gradually increasing in number.In the surveyed written memos of the XIV-XV centuries, there are few innovations, they are recorded in the monuments of these centuries: повод ‘plaintiff in court’, найда, пeрeхрыст, шкандыба, розбій ‘robber’, розвідь ‘prostitute’ and many others. In the monuments of different times we find the names of the subjects of action as a collective concept: народъ, полонъ ‘prisoners; збридъ, сторожа, глота ‘crowd’ and some others. The researched monuments also record the attributive names of animals ((скокъ,’horse’, кокотъ ‘rooster’, подлиз ‘snake’, туркот ‘pigeon’, підпалок "quail", квак ‘waterfowl species’, окрута ‘larva’, дойда ‘hunting dog’, etc). From the XI century, the names of plants are documented: сад, плав ‘cork tree’, розрив ‘name of miraculous grass’, приворот, запах ‘white mushroom’, шелест, підвоя, ‘black nightshade’, остуда ‘tansy ordinary’, etc. The article also describes the history of adjective nouns of living nature and nouns of the common gender.Selected linguistic facts give grounds to assert that the zero-suffixal creation of names of living nature from ancient times to the present day is quite common, which has had a significant impact on the formation of the entire derivation system of the Ukrainian noun. The vast majority of names of persons belong to stylistically neutral vocabulary, although in the vernacular there are more and more structures with a negative evaluation value, as well as in the names of animals and plants.
