The Chinese word 海鲜 (hǎixiān), meaning "seafood", is a compound noun formed through semantic combination. It consists of two characters: 海 (hǎi), meaning "sea" or "ocean", and 鲜 (xiān), which in this context means "fresh delicacy" or "savory food". Together, they create a modifier-head structure where "海" (sea) modifies and specifies the type of "鲜" (delicacy), directly and logically indicating "delicacies from the sea". This formation is a classic example of how Chinese commonly creates new words by combining meaningful root characters to convey a clear, composite concept.
