Linguistic career

Both Tolkien's academic career and his literary production are inseparable from his love of language and philology. He specialized in English philology at university and in 1915 graduated with Old Norse as his special subject. He worked on the Oxford English Dictionary from 1918 and is credited with having worked on a number of words starting with the letter W, including walrus, over which he struggled mightily. In 1920, he became Reader in English Language at the University of Leeds, where he claimed credit for raising the number of students of linguistics from five to twenty. He gave courses in Old English heroic verse, history of English, various Old English and Middle English texts, Old and Middle English philology, introductory Germanic philology, Gothic, Old Icelandic, and Medieval Welsh. When in 1925, aged thirty-three, Tolkien applied for the Rawlinson and Bosworth Professorship of Anglo-Saxon at Pembroke College, Oxford, he boasted that his students of Germanic philology in Leeds had even formed a " Viking Club ". He had a certain, if imperfect, knowledge of Finnish.

Privately, Tolkien was attracted to "things of racial and linguistic significance", and in his 1955 lecture English and Welsh, which is crucial to his understanding of race and language, he entertained notions of "inherent linguistic predilections", which he termed the "native language" as opposed to the "cradle-tongue" which a person first learns to speak. He considered the West Midlands dialect of Middle English to be his own "native language", and, as he wrote to W. H. Auden in 1955, "I am a West-midlander by blood (and took to early west-midland Middle English as a known tongue as soon as I set eyes on it)."
