The word **猜谜** (cāimí) is a compound formed by combining the verb **猜** (cāi), meaning "to guess," with the noun **谜** (mí), meaning "riddle" or "puzzle." This follows a common grammatical structure in Chinese where a verb is paired with its object to create a new term for an activity. Thus, **猜谜** literally means "to guess riddles" and refers to the act or activity of solving puzzles, commonly used for traditional lantern riddles or any riddle-solving game.
