At which Oxford college did J.R.R. Tolkien study as a student?

J.R.R. Tolkien studied at Exeter College, Oxford.

Tolkien entered Exeter College in 1911 as an undergraduate at the University of Oxford. He first studied Classics before moving into the English Language and Literature course, where his aptitude for languages and medieval texts became increasingly important.

Exeter College was founded in 1314 and is one of Oxford's historic colleges. Tolkien's time there preceded his later professional connection with other Oxford colleges, which can make the college names easy to confuse.

Tolkien later taught at Pembroke College and served as Merton Professor while associated with Merton College. Those later appointments do not change the answer for his undergraduate college: he studied at Exeter. This distinction separates his student years from his subsequent academic career.
