The word 天堂 is formed by combining two characters, each contributing a core concept to create a new, unified meaning. The first character, 天, represents "sky" or "heaven", evoking the vast, elevated, and celestial realm. The second, 堂, signifies a "hall", "main room", or a dignified and spacious building. By fusing these ideas, the compound visually and conceptually constructs the notion of a "heavenly hall", a majestic, divine abode or paradise, directly translating the abstract idea of a perfect, otherworldly dwelling into a tangible architectural metaphor.
