The novel had its inception in a lecture Woolf gave to the National Society for Women's Service on January 21, 1931, an edited version of which would later be published as "Professions for Women". Having recently published "A Room of One's Own", Woolf thought of making this lecture the basis of a new book-length essay on women, this time taking a broader view of their economic and social life, rather than focusing on women as artists, as the first book had. As she was working on correcting the proofs of "The Waves" and beginning the essays for "The Common Reader, Second Series", the idea for this essay took shape in a diary entry for 16 February 1932: "And I'm quivering & itching to write my--whats it to be called?--'Men are like that?'--no thats too patently feminist: the sequel then, for which I have collected enough poweder to blow up St Pauls. It is to have 4 pictures" (capitalization and punctuation as in manuscript). The reference to "4 pictures" in this diary entry shows the early connection between "The Years" and "Three Guineas", which would, indeed, include photographs. On 11 October 1932, she titled the manuscript "THE PARGITERS: An Essay based upon a paper read to the London/National Society for Women's Service" (capitalization as in manuscript). During this time, the idea of mixing the essay with fiction occurred to her, and in a diary entry of 2 November 1932, she conceived the idea of a "novel-essay" in which each essay would be followed by a novelistic passage presented as extracts from an imaginary longer novel, which would exemplify the ideas explored in the essay. Woolf began to collect materials about women's education and lives since the later decades of the 19th century, which she copied into her reading notebooks or pasted into scrapbooks, hoping to incorporate them into the essay portions of "The Pargiters" (they would ultimately be used for "Three Guineas").
