A Man Named Dave Vocabulary

A word I found in A Man Named Dave that I am unfamiliar with is 'raved'. The sentence is, "When I was younger, mother would drag me out of bed in the middle of the night, have me stand in front of her as she poured herself glass after glass and raved on for hours." (Pelzer 14) After looking it up, I now know that raved means to talk wildly, as in delirium. This book also has other good vocabulary words as well.
