Compared meaning: a feeling of happiness (noun).

比较义项：快乐、愉悦的感觉（名词）。

• pleasure

  The mildest and most general term; often used in polite social formulas ('it's a pleasure to...') or for everyday enjoyment, not necessarily intense.

  语气最温和、最笼统的一个词；常用于礼貌的社交套语（如“it's a pleasure to...”）或日常的享受，不一定很强烈。

  It was a pleasure to meet your family last weekend.

  上周末能认识你的家人真是荣幸。

• joy 本词

  Describes a deep, pure inner happiness, often lasting or heartfelt, used for meaningful moments and states of being rather than as a polite phrase.

  指深沉、纯粹的内心快乐，往往持久且发自内心，用于表达有意义的时刻或状态，而不是礼貌客套。

  Watching the children play brought her great joy.

  看着孩子们玩耍让她感到无比快乐。

• delight

  A strong, often visible or expressed pleasure, typically a spontaneous reaction to something specific or surprising; common in 'squeal/shout with delight'.

  指强烈、常常外露或表达出来的高兴，通常是对某件具体或令人惊喜的事的即时反应；常见于“squeal/shout with delight”这类搭配。

  The children squealed with delight when they saw the puppy.

  孩子们看到小狗时高兴得尖叫起来。

Pleasure, joy, and delight all mean a happy feeling, but the strength differs. Pleasure is the mildest and most general, often just a polite phrase. Joy is a deep, heartfelt happiness, often lasting. Delight is a strong, visible happiness, a sudden reaction to something surprising.

这三个词都表示“快乐”这种正面情绪，词义相近，但语气和使用场合略有不同：pleasure 语气温和、常用于社交客套表达；joy 指发自内心、较深沉持久的快乐；delight 则指因某件具体或意外的事而产生的强烈、外露的高兴，常伴随惊呼或明显反应。

Compared meaning: to feel or cause great happiness (verb).

比较义项：使高兴，感到高兴（动词）。

• joy 本词

  Used here as a transitive verb meaning to make someone feel happy; the subject is the cause, not the person feeling happy. Fairly uncommon and somewhat literary compared to its noun use.

  此处作及物动词，表示使某人感到快乐；主语是原因而非感到高兴的人。这种动词用法不太常见，比其常见的名词用法更显文学化。

  Watching the children play brought her great joy.

  看着孩子们玩耍给她带来了极大的快乐。

• rejoice

  An intransitive verb meaning to feel or show great happiness openly, often together with others; stronger and more formal, typically used for big news, victories, or celebrations.

  不及物动词，表示明显地感到或表现出极大的高兴，常常是与他人一同表现出来；语气更强烈、更正式，常用于重大消息、胜利或庆祝场合。

  The whole town rejoiced when the team won the championship.

  当球队赢得冠军时，全镇的人都欢庆起来。

Joy and rejoice both relate to feeling happy, used here as verbs. Joy, uncommon and literary, means to make someone happy; the subject causes it. Rejoice means to feel or show happiness openly, and is stronger, more formal. Joy as a noun is not compared.

两词都表示因某事而高兴，但 joy 常用于使役结构（某事使某人高兴），语气平实；rejoice 是不及物动词，指发自内心地为某事欢欣庆祝，语气更强烈、更正式，常用于重大好消息或庆典场合。不比较 joy 用作名词表示“喜悦”这一常见用法。
