aristocratic
Having the elegant style or manners of very high social class.
Aristocratic means belonging to or characteristic of the aristocracy, the highest social class in many historical societies. Aristocrats were families who held titles like duke, duchess, baron, or countess, often owning large estates and wielding significant political power. In medieval Europe, aristocratic families controlled vast lands, and their children grew up learning refined manners, classical languages, and skills like horseback riding and dancing.
The word also describes qualities or behaviors associated with this upper class: refined taste, elegant manners, and an air of distinction. An aristocratic manner might include speaking precisely, carrying yourself with confidence, and showing familiarity with art, literature, and classical music. Someone might describe a person as having aristocratic features (meaning refined, elegant facial characteristics) or an aristocratic bearing (meaning they carry themselves with natural dignity).
While aristocracies have lost most of their political power in modern democracies, the word still describes a certain style or refinement. You might call a beautifully decorated mansion aristocratic, or say someone has aristocratic tastes if they prefer fine art and classical music. The word can sometimes suggest snobbishness or aloofness, but it can also simply mean elegant, refined, or distinguished.
