The compound word 幽会 (yōuhuì, "secret rendezvous" or "tryst") is formed through semantic combination, where 幽 conveys meanings of "secluded," "dark," "deep," or "secret," and 会 means "to meet" or "a meeting." Together, they create a new, nuanced meaning that is more specific than the sum of its parts: a secret, often romantic, meeting held in a private or secluded place, carrying connotations of intimacy and confidentiality. This formation is a classic example of how Chinese logographs combine to express abstract or complex concepts through suggestive imagery—here, the imagery of a "secluded meeting."
