Lexical Approach has enabled huge quantities of natural spoken discourse to be analyzed, which has reinforced the theory that much of our language output is not created from the smallest components but comes in the form of multi-word "chunks" of language. Reflected in oral language, Small Words, as one of the function words, are stored and produced as such forms. This book is devoted to fully investigate fluency strategic devices, which some discourse markers named "Small Words" function as. By using both quantitative and qualitative methods the author aims at tracking down if there exists a positive correlativity between Small Words and oral fluency.
