The Chinese word **防水 (fángshuǐ)**, meaning "waterproof" or "water-resistant," is a compound formed by combining two characters: **防 (fáng)**, which means "to prevent" or "to guard against," and **水 (shuǐ)**, which means "water." It follows a common grammatical structure in Chinese where a verb (**防**) is directly paired with its object (**水**) to create a new term that describes the action's purpose—in this case, the prevention or resistance of water. This logical, semantic combination makes the word's meaning immediately clear to a reader familiar with the individual characters.
