The Chinese word 火箭 is formed by combining the character 火, meaning "fire", with 箭, meaning "arrow", to create a compound that visually and conceptually represents a rocket as a fire-propelled arrow. This formation relies on the direct semantic fusion of both characters, where 火 describes the explosive force and 箭 outlines the projectile shape, together evoking the essence of the object without requiring abstract grammatical constructs.
