  Means formally holding an official title of nobility, such as Lord or Sir, focusing on legal or social rank rather than lineage or manner.

Imperial, noble, titled, and regal all relate to royal or aristocratic rank: imperial to an empire, noble to aristocratic birth, titled to holding a title like Lord, and regal to a king's manner. Not compared: noble meaning virtuous, or titled as a verb.

这四个词都可用来形容与帝王、贵族身份或气派有关的人或事物，但侧重点不同：imperial强调帝国或皇帝本身，noble强调贵族血统出身，titled强调正式拥有爵位，regal强调具有帝王般的气度。这里不比较noble表示“品德高尚的”这一义项，也不比较titled作动词表示“给……命名或加标题”的用法。
