Introductory elements of the semantics of "recollection": semantic-functional and dynamic aspects

The article is devoted to the insufficiently explored introductory elements - nuclear means of expression of the modus category «recollection». The paper deals with the extent of their representation in the scientific literature; special attention is paid to the semantic features of the investigated introductory words, the possibility of their interchangeability, as well as the definition of their functions in a text. In addition, the author attempts to examine the dynamic processes in the introductory words to semantics «recollection»: compare the frequency of their use in the texts of the two time intervals (XVIII-XIX centuries, and the last two decades at the turn of XX-XXI centuries.)
