Latin

The article highlights differences between root morphemes and radixoids of Latin origin in the structure of linguistic terms and specific units of term formation – term elements.

Classical languages in the scientific communication of the early modern period could be the language of written text, the source of borrowed vocabulary (these functions are now lost); the foundation for creating lists and symbols (these systems are used but are hardly ever replenished); sources of morpheme borrowing (such morphemes are widely used in term formation of the modern languages).

The material of the study presents adjectives of Latin origin with final-alny in modern Russian. This final is a morphemic complex. This can be interpreted in three ways, depending on the word-formation relations of specific adjectives. It may be a single suffix; a suffix with a submorph -n-; a suffix -n- attached to the root in -al-.
