Meaningful adverbs are traditionally assigned a separate place at the adverbial system, calling them a semantic group or semantic category, which expresses the quality or intrinsic property of a dynamic (verb) or static (adjective) trait. In the most recent grammatical descriptions of the Ukrainian literary language, the definitive adverbs are separated into a large semantic-syntactic category on the basis of those relations established as a result of the use of the lexical meanings of adjectives in the adverbial position, since the adjective signifier is an adverbial in its adverbial function. The declarative adverbs are directed to the area of expression of the adverbial (circumstantial) meanings through some of the common signs with the adjectives: expressive (though not immanent, but transposed through the adjective) attributive value, the degree of expression of the qualitative sign, the adverbial connection with the reference, which does not give a reason to consider them the semantic-syntactic core of the adverb as part of the language. The article is devoted to the consideration of formal and syntactical positions of meaningful adverbs in the Ukrainian language. The position of the verb unmanageable minor term of the sentence is considered as a specialized formal-syntactical position of qualitative-meaning adverbs; the position of the adverbial minor member of the sentence of qualitative-relative signifiers; the position of the adjective-driven minor term of the sentence of significant space adverbs; the verbal position of an unmanaged minor member of the adverb’s sentence of mode of action and measure and degree.
