Throughout the novel, nouns are amended with an -ed ending and I believe turned into verbs or adjectives.

“a pair of spindly legs (now flanneled and crossed)” (7)
“in the middle of a landscaped campus, by ivied galleries” (9)
+ more

Other repetitions which I noticed were: clocks, authors (Tolstoy, Dostoevsky, Pushkin, Chekhov +others), changing residence
