The use of dialogues is prevalent in fiction , but this technique can also be found in poetry, non-fiction, films and drama . The dialogue has several purposes, such as advances the plot of a narrative , and reveals the characters that cannot be understood otherwise. Further, it presents an exposition of the background or the past events and creates the tone of a narrative. Its usage can also be seen in the modern literary works, where it colors the personalities of the characters, creates a conflict, highlights the vernacular and moves the storyline forward. Moreover, dialogue makes a literary piece interesting and alive, and gives enjoyable experience to the readers.
Saussure's linguistic ideas are still considered important for their time but have suffered considerably subsequently under rhetorical developments aimed at showing how linguistics had changed or was changing with the times. As a consequence, Saussure's ideas are now often presented by professional linguists as outdated and as superseded by developments such as cognitive linguistics and generative grammar or have been so modified in their basic tenets as to make their use in their original formulations difficult without risking distortion, as in systemic linguistics . That development is occasionally overstated, however; Jan Koster states, "Saussure, considered the most important linguist of the century in Europe until the 1950s, hardly plays a role in current theoretical thinking about language,"  More accurate [ speculation? ] would be to say that Saussure's contributions have been absorbed into how language is approached at such a fundamental level as to be, for many intents and purposes, invisible, much like the contributions of the Neogrammarians in the 19th century. Over-reactions can also be seen in comments of the cognitive linguist Mark Turner  who reports that many of Saussure's concepts were "wrong on a grand scale". It is necessary to be rather more finely nuanced in the positions attributed to Saussure and in their longterm influence on the development of linguistic theorizing in all schools; for a more recent rereading of Saussure with respect to such issues, see Paul Thibault.  Just as many principles of structural linguistics are still pursued, modified and adapted in current practice and according to what has been learnt since about the embodied functioning of brain and the role of language within this, basic tenets begun with Saussure still can be found operating behind the scenes today [ citation needed ] .
