  Describes objects or materials that resist damage or wear over time; a practical, everyday word for products, fabrics, or equipment, not for relationships or feelings.

  这个耐用的手提箱经受住了在机场里多年的粗暴搬运，仍没有一丝划痕。

• long

  A general, neutral word for duration; pairs with time spans, events, or relationships (a long wait, a long friendship) without implying resistance to damage or a lifetime limit.

  泛指时间跨度长的中性词，可修饰等待、事件或人际关系（如漫长的等待、长久的友谊），并不暗示“耐用”或“持续一生”。

  Doctors say most patients make a full recovery after a long illness.

  医生说，大多数病人在经历一场长期疾病后都能完全康复。

• lifelong

  Emphasizes that something lasts for a person's entire life, often used for deep commitments, passions, or conditions; more formal and emphatic than 'long', and always placed before the noun.

  强调某事持续一个人的一生，常用于深厚的承诺、热爱或病症，语气比 long 更正式、更强烈，且通常只能放在名词前面。

  Her lifelong passion for painting began when she was just five years old.

  她对绘画的毕生热爱，始于她五岁那年。

Durable, long, and lifelong describe something lasting a long time. Durable is a practical word for objects that resist damage, like fabrics, not relationships. Long is the neutral word for duration, used for time spans, events, or relationships. Lifelong stresses lasting a whole life.

这三个词都表示“持续时间长”，但侧重点不同：durable 强调物品经久耐用、不易损坏；long 泛指时间跨度长，语气中性；lifelong 特指持续一生，语气更强、更正式。这里不比较 long 表示空间长度（如“长路”）的义项。
