In Samuel Beckett's novel "Watt," the protagonist, Watt, often struggles with self-identity and the meaning of things around him. This existential crisis leads him to try out different names for objects and himself, much like a person might try on various hats to find the right fit. This metaphor emphasizes Watt's search for meaning and his need for linguistic expression in a world that feels chaotic and devoid of clarity.

Watt's experimentation with names reflects a deeper longing for understanding and connection. Just as a hat can change one’s appearance and persona, the act of renaming represents his quest for self-definition amidst confusion. This highlights the overarching theme of language's power and its limitations in capturing the essence of one's identity and experiences.
