The word 旅途 is formed by combining two characters, each contributing a core concept to create a unified meaning. The first character, 旅 (lǚ), primarily conveys the idea of a journey or travel. The second character, 途 (tú), means a road, path, or way. When fused, they create the compound idea of "the road of a journey", poetically encapsulating the entire experience of a trip, not just the act of traveling, but the route, the course, and the time spent in transit, evoking the sense of an ongoing passage from one point to another.
