The word "安检" (ānjiǎn) is a compact compound noun formed by combining two meaningful characters: "安" (ān), which means "safe" or "secure," and "检" (jiǎn), which means "check" or "inspect." This structure follows a common pattern in Modern Chinese where two monosyllabic morphemes are merged to create a new, specific term—in this case, a shorthand for "安全检查" (ānquán jiǎnchá), meaning "security inspection." The resulting word efficiently conveys the core concept of a procedure (checking/inspecting) for a specific purpose (safety/security), typical of the language's tendency toward logical and economical word formation.
