"She [Mrs. Bertram] was a woman who spent her days in sitting, nicely dressed, on a sofa, doing some long piece of needlework, of little use and no beauty, thinking more of her pug than her children, but very indulgent to the latter when it did not put herself to inconvenience..."[10]
— Jane Austen, Mansfield Park (1814)
Irony is one of Austen's most characteristic and most discussed literary techniques.[11] She contrasts the plain meaning of a statement with the comic, undermining the meaning of the original to create ironic disjunctions. In her juvenile works, she relies upon satire, parody, and irony based on incongruity. Her mature novels employ irony to foreground social hypocrisy.[12] In particular, Austen uses irony to critique the marriage market.[13] Perhaps the most famous example of irony in Austen is the opening line of Pride and Prejudice: "It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife." At first glance, the sentence is straightforward and plausible, but the plot of the novel contradicts it: it is women without fortunes who need husbands and seek them out. By the end of the novel, the truth of the statement is acknowledged only by a single character, Mrs. Bennet, a mother seeking husbands for her daughters, rather than the entire world.[14] Austen's irony goes beyond the sentence level. As Austen scholar Jan Fergus explains, "the major structural device in Pride and Prejudice is the creation of ironies within the novel's action which, like parallels and contrasts, challenge the reader's attention and judgment throughout, and in the end also engage his feelings."[15] Austen's irony illuminates the foibles of individual characters and her society. In her later novels, in particular, she turns her irony "against the errors of law, manners and customs, in failing to recognize women as the accountable beings they are, or ought to be".[16]
