Delving into the complexity of puns, this chapter challenges traditional views on the metaphysics of words by examining how puns blur the distinctions between word types and tokens. The speakers analyze examples like 'sales' and 'reaction' to showcase how puns introduce ambiguity and indeterminacy in determining word types, presenting a unique metaphysical challenge. Through this analysis, the chapter sheds light on the intricate relationship between language, ontology, and the philosophical debate between nominalism and type-token realism.
