The Dictionary of Lost Words is the debut novel by Australian writer Pip Williams, published in March 2020.

She spends her childhood under the table in the Scriptorium, where James Murray and his team of lexicographers, including her father, are compiling the Oxford English Dictionary.

[3] In addition to being published in standard formats (paperback, ebook, audio book), a dyslexic edition is available.

[3] In reviewing the book for The Sydney Morning Herald, Jo Case says "In The Dictionary of Lost Words, Pip Williams combines the storytelling scale and intimate detail of a 19th-century novel with the sensibility of now – and a cast of richly realised characters and relationships that are a pleasure to spend time with".

[8] Other reviewers discussed the novel's elevation of language, with Book Reporter referring to it as "the novel [word lovers and linguists] have been waiting for without even realizing it"[9] and Booklover Book Reviews saying it "reminds us of the power of words, to harm and control, but also to bridge gaps, to empower and to bring about change for the better".
