This paper deals with the concept of unity in language science from the point of view of linguistic analysis proper and demonstrates that the description of languages in not made up of discrete levels but rather involves facets which are inextricably entwined. Syntax, semantics and the lexicon have no functional autonomy and can therefore not be studied separately one from the other. By the very nature of their integration they contribute to the usages of the predicate. A usage is made up of a set of properties of all kinds which characterize a pattern of arguments described with the help of object classes and its acualization.
