The article examines the issue of (quasi-)synonymy in Latin morphosyntactic constructions, focusing on the relationship between simple verbs, analytic verbo-nominal collocations, and incorporated verbal forms. Although Latin is traditionally classified as a synthetic and inflectional language, the authors demonstrate that it also contains structures typical of analytic and incorporating language types. The study is centered on semantic clusters in which several formally different constructions express closely related meanings. Examples include combinations of simple verbs, support verb constructions, and lexicalized incorporated forms. The main objective of the research is to determine whether these constructions are truly synonymous or whether each occupies a distinct functional position within the language system. The authors show that analytic constructions (or support verb constructions) are not redundant alternatives to simple verbs. On the contrary, they serve important grammatical and semantic purposes. Such constructions make it possible to express aspectual distinctions, represent different stages of an action, and provide greater syntactic flexibility. In particular, verbo-nominal collocations allow modification of the nominal component, relativization, and secondary predication, which are often unavailable in simple verbal forms. Special attention is paid to the phenomenon of noun incorporation in Latin. While Latin does not display productive incorporation at the macro-typological level, the article demonstrates the existence of marginal and non-productive incorporation patterns at the micro-level. A particularly significant finding is the phenomenon of retransitivization, in which incorporated verbs preserve or regain transitivity, thus challenging traditional typological expectations. The empirical basis of the article is a corpus analysis of twelve verbal clusters drawn from the PHI-5 database. The constructions are examined according to lexical semantics, argument structure, frequency, diachronic distribution, and the use of finite and non-finite forms. The results indicate that full synonymy is relatively rare. In many cases, the constructions differ considerably in meaning, syntactic behavior, and frequency of use. The article concludes that the coexistence of simple verbs, collocations, and incorporated forms is functionally motivated rather than excessive. Each construction performs specific semantic, syntactic, and pragmatic functions, reflecting the interaction of synthetic and analytic tendencies in the development of Latin.
