Explanation:
The narrator in novel “Invisible Man” is referred to as an “invisible man” due to his perception of being unrecognized and marginalized as a black man in a white-dominated society. The title itself is symbolic of the narrator’s lack of visibility and identity in society, as he is constantly ignored or discriminated against based on his skin color. The term “invisible” also connotes the idea of transparency, as if the narrator is a ghost or a fleeting apparition that is not fully present or acknowledged. This notion is reinforced by the narrator’s own description of himself, as he states that he is “invisible, understand, simply because people refuse to see me.”
