The Chinese word 海港 (hǎigǎng), meaning "seaport," is a straightforward compound formed by combining two independent characters: 海 (hǎi), meaning "sea," and 港 (gǎng), meaning "port" or "harbor." It follows a common grammatical structure in Chinese known as a modifier-head compound, where the first character 海 acts as a modifier to specify the type of port described by the head character 港. Thus, the term literally and logically translates to "sea-port," explicitly distinguishing it from other types of ports like river ports (河港).
