Ernest Weekley (27 April 1865 - 7 May 1954) was a British philologist, best known as the author of a number of works on etymology. His An Etymological Dictionary of Modern English (1921; 850 pages) has been cited as a source by most authors of similar books over the 90 years since it was published. From 1898 to 1938, he was Professor of Modern Languages at the University of Nottingham. He married Frieda von Richthofen in 1899. Together they had three children: Charles Montague (born 1900), Elsa Agnès (born 1902) and Barbara Joy (born 1904). Weekley divorced Frieda in 1913 following her elopement with D. H. Lawrence.
