What is the author's style in Old Possum's Book of Practical Cats by T. S. Eliot?

Eliot used a lot of words that have fallen out of common use in the intervening years. This book is an interesting lesson in older words, such as terpsichorean. This word appears in The Song of the Jellicle Cats story and refers the dancing abilities of the Jellicle Cats.

The names of the cats are fascinating and, while they may not be names you would ever select for a cat, they are unique. Grumbuskin and Bombalurina are not typical names for cats, as most people now prefer to give their cats the simple names that Eliot mentions in his chapter, "The Naming of Cats."
