I'm not a regular reader of
Tolkien Studies but perhaps I should be. I just came across this scholarly article by Professor Michael Drout which defends Tolkien against Modernist criticism by way of linguistic analysis.
Tolkien's Prose Style and its Literary and Rhetorical Effects
There's some intriguing connections with Shakespeare's
King Lear and an analysis of Tolkien's defense of kingship, to say nothing of an insightful suggestion about Denethor and the Witch King.
As a rout of Modernist antipathy to Tolkien it should make many a Downer's day.
