The article analyzes the state of lexicographic modeling of modern Slavic morphemics, primarily the Ukrainian language. The development of Ukrainian morphemography over the past 40 years has been traced. Particular attention is paid to the computer morpheme and word‑formative fund of the Ukrainian language, which was created and is being developed by researchers of the Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine in Kyiv. Common parameters of the form and semantics of roots and affixes are highlighted, which can become a basis for comparative studies. It is noted that, in contrast to Ukrainian morphemology, the morphemic dictionaries of other Slavic languages rarely present complex morphemic units: pairs and chains of affixal morphemes, affixal surroundings (lattices) of roots, models of the morphemic structure of words and morphemic nets for constructing words of certain parts of speech. The need to create a common factual basis, a common theoretical and methodological foundation for carrying out comparative studies on morphemics is emphasized. Only under this condition can we expect reliable conclusions about the typology and characterology of Slavic morphemics in general and morphemics of a certain Slavic language in particular.

Apart from verbs, languages possess morphemes which are related to time without this connection being obvious to the speakers or felt by them. Such is the case of the articles, certain prepositions, conjunctions and particles. In the present article, I analyse particularly the indefinite and definite articles. These create a sequence that actualises a noun and then reactualises it, giving it thereby a past. Thus, I describe actualisation with the help of articles, but I also take up to discussion sequential and contextual actualisation. The examples I quote come mainly from French but, since actualisation is a general linguistic phenomenon, some of them represent languages which are structurally different from each other. The temporality rendered by the grammatical morphemes can express either past time or future time.

The issue of the morphemic analysis of medical terminology is a crucial factor in terms of translation strategies and compilation of a terminological dictionary. The research was conducted in the context of author’s current lexicographical work called as English-Ukrainian-Russian defining dictionary of dental terms. To provide the user of the dictionary with reliable techniques to construct the meaning of terms, morphemes relative frequency in the area of dentistry have been determined.
