There are myriad vocabulary words in “The Man Who Was Poe," but these I like because they communicate new ideas about familiar words or new words for familiar words.
Baleful means in a threatening manner or foreshadowing of evil or some other tragic developments.
Brawl as a noun is a noisy fight. As a verb, brawl means to quarrel in a noisy, angry, or disruptive way.
Insinuate means to insert oneself or one’s opinion in a subtly way.
Piqued means to cause or feel anger or resentment.
Sordid can mean unorthodox or dishonest. It can also mean run down and disgusting.
