The word 隐蔽 is formed by combining two characters, each contributing a layer of meaning to create a unified concept. The first character, 隐 (yǐn), carries the core idea of hiding, concealing, or receding from view. The second character, 蔽 (bì), adds the specific notion of covering, shielding, or obscuring. When joined, they create a compound where the meaning of 隐 is elaborated and intensified by 蔽, resulting in a complete idea that means "to conceal by covering up" or "to take cover", implying an active, thorough, and often physical act of hiding or remaining hidden.
