Perhaps the most surprising fact about the “sentimental novel” of the eighteenth century is that the category is not just the useful invention of literary historians. The declaration “A Sentimental Novel” actually appeared on the title pages of many works of fiction of this period, and was particularly common during the 1770s and 1780s. Yet the novels that advertised themselves in this way are no longer read, even if they might once have been largely responsible for the poor reputation that “sentiment” earned, and for a change in the meaning of the word “sentimental” recorded by the Oxford English Dictionary. At the end of the eighteenth century the use of “sentimental” turned from the approbatory to the pejorative; from “exhibiting refined and elevated feelings” to “addicted to indulgence in superficial emotion.” Yet clearly this change cannot have been certain even by the 1790s, when some novels were still willing to declare themselves “sentimental.”
