Philology was J.R.R. Tolkien’s academic field at Oxford when he developed much of Middle-earth’s mythology. Philology studies language through historical texts, including how words, sounds, and meanings change over time.
Tolkien became a professor of Anglo-Saxon at Oxford in 1925 and later held the Merton Professorship of English Language and Literature. His scholarship included Old English, Middle English, and medieval literature. This work gave him an unusually detailed understanding of the languages and stories that influenced his fiction.
Tolkien’s professional interests and creative writing were closely connected. He often began with a word, a sound pattern, or a linguistic problem and built stories around it. His invented languages therefore have histories and relationships rather than functioning merely as secret codes.
Tolkien is also frequently described as a medievalist and a linguist, but philology is the specific traditional academic discipline associated with his Oxford career. Archaeology and geology are separate fields and did not define his university appointments.
