The Chinese word **剃刀 (tìdāo)**, meaning "razor," is a straightforward **compound word** formed by combining two meaningful characters: **剃 (tì)**, which means "to shave" or "to scrape off," and **刀 (dāo)**, which means "knife" or "blade." The construction follows a common **modifier-modified** or **purpose-description** pattern in Chinese, where the first character specifies the function ("shaving") and the second character identifies the object category ("blade"). Thus, the compound literally and logically translates to "a shaving blade" or "a blade for shaving."
