What is the author's style in Portnoy's Complaint by Philip Roth?

Several extended passages are written in an almost ranting style, as though the narrator is speaking from a place of raw, surging emotion (usually anger or frustration). The narrator's expansive vocabulary creates the sense not only of powerful intelligence and memory, but also on some level the sense that the narrator is desperately trying to control those surging emotions by intellectualizing them, disguising raw feeling with cleverness. There is also the incorporation of a great many Yiddish words and terms.
