What was J.R.R. Tolkien’s first professional job after university?

J.R.R. Tolkien’s first professional job after university was assistant lexicographer on the staff of the Oxford English Dictionary.

After serving in the First World War, Tolkien joined the project in 1919. He worked on words beginning with the letter W, investigating origins, historical forms, meanings, and relationships across Germanic languages. This demanding work gave him practical experience in the kind of historical language study that later defined his academic career.

The Oxford English Dictionary project helped bridge Tolkien’s early philological training and his later teaching. He subsequently worked as a reader and professor at the University of Leeds before joining Oxford. His OED experience is often mentioned because it shows that his fascination with words was not merely a fictional hobby: language history, sound change, and etymology were central to his professional life.
