The Chinese word 掩体 (yǎntǐ), meaning "bunker" or "protective shelter," is a compound noun formed through semantic combination. It consists of the character 掩 (yǎn), which means "to cover," "to conceal," or "to shield," and 体 (tǐ), which means "body" or "structure." When combined, these characters create a logical and descriptive concept of a "covering structure" or a "shielded body," directly referring to a fortified position designed to protect personnel or equipment from enemy fire or explosives, thus exemplifying a common Chinese word-formation method where two meaningful components merge to produce a new, specific term.
