The word **导游** (dǎoyóu), meaning "tour guide," is a transparent compound formed by combining two meaningful characters: **导** (dǎo), which means "to guide" or "to lead," and **游** (yóu), which means "to travel" or "to tour." Together, they create a word where the first character describes the action (**guiding**) and the second specifies the domain or object of that action (**travel/touring**), resulting in the literal and functional concept of "one who guides a tour" or the activity itself. This structure is a classic example of a verb-object semantic relationship in Chinese word formation.
