What was J.R.R. Tolkien’s academic field of study and research?

J.R.R. Tolkien’s academic field of study and research was philology.

Philology examines languages through historical texts, with particular attention to how languages develop and relate to one another. Tolkien studied Classics, English language, and Germanic philology, and he became an influential scholar of Old and Middle English. His academic interests included Old Norse, Welsh, Gothic, and other languages connected to the history of English.

This background strongly shaped his fiction. Tolkien often built invented languages first or alongside the stories and histories associated with them. Names, sound patterns, writing systems, and supposed linguistic relationships help make Middle-earth feel like a world with a deep past.

Philology is sometimes confused with linguistics, literary criticism, or mythology. Those subjects overlap, but philology specifically emphasizes historical language and the interpretation of texts. Tolkien was also a writer and professor, yet philology most precisely identifies the scholarly discipline at the heart of his training.
