• loyalty 本词

  A broad, everyday word for faithfulness or devotion to any person, animal, group, brand, or cause; often emotional and personal rather than formal.

  The dog showed great loyalty by waiting outside every day.

  这只狗每天都在外面等着，表现出极大的忠诚。

• allegiance

  A formal, often ceremonial loyalty owed to a country, leader, or organization; typically the object of verbs like 'swear' or 'pledge', implying a legal or moral duty.

  忠心指对国家、领袖或组织所负的正式、带仪式性质的忠诚，常与“宣誓”“效忠”等词搭配，含有法律或道义上的义务。

  Soldiers swear allegiance to their country before joining the army.

  士兵在入伍前要向国家宣誓效忠。

Loyalty and allegiance both mean being faithful to someone or something. Allegiance is more formal, often owed to a country or leader, and used with 'swear' or 'pledge'. Loyalty is broader and more everyday, used for people, animals, or brands, and feels more personal.

loyalty 和 allegiance 都表示对某人或某事物的忠诚，容易混淆；但 allegiance 更正式，多指对国家、领袖或组织所负的效忠义务，常与“宣誓”搭配；loyalty 的适用范围更广，可用于人、动物、品牌等任何对象和关系，语气更日常、更感性。
