leap

Compared meaning: a big jump (noun).

比较义项：跳跃（名词）。

• leap 本词

  Leap denotes one large, dramatic jump and is common in figurative expressions for a sudden, big advance or change, not just physical jumping.

  leap 指一次幅度很大、极具戏剧性的跳跃，也常用于比喻性的表达，表示突然而巨大的变化或进步，而不仅限于身体上的跳跃。

  The invention of the internet was a giant leap in human communication.

  互联网的发明是人类通讯领域的一次巨大飞跃。

• bound

  Bound suggests a light, springy jump, often one of several in quick succession, and typically describes animals or people moving energetically.

  bound 指轻盈而富有弹性的跳跃，往往是连续快速跳跃中的一次，通常用来描述动物或人充满活力地移动。

  The kangaroo crossed the field in three enormous bounds.

  那只袋鼠以三次巨大的跳跃穿过了田野。

Leap and bound can both mean a big jump. Leap means one large, dramatic jump, often used figuratively for a sudden big change. Bound means a light, springy jump, often one of several in a row, typically for an animal or person moving energetically.

这两个词都可以表示“幅度较大的跳跃”，但语气和使用场景有所不同：leap 强调一次决定性的、往往幅度很大的跳跃，也常用于比喻意义，表示突然而巨大的变化或进步；bound 则多指轻盈而富有弹性的跳跃，常用于描述动物或人连续快速地跃过某段距离。这里不比较 bound 表示“受约束的／被迫的”（如 bound by a leash）或“开往……的”（bound for）等其他意义。

Compared meaning: to jump or leap up suddenly (verb).

比较义项：突然跳起，跃起（动词）。

• spring

  Spring highlights a sudden, quick movement triggered by surprise or reaction, moving from stillness to motion in an instant; it doesn't focus on distance or height.

  spring 强调动作发生得突然、迅速，通常是受到惊吓或刺激后从静止瞬间转为行动；它并不侧重跳跃的距离或高度。

  The dog sprang forward the instant it spotted a squirrel in the yard.

  那只狗一看到院子里的松鼠，就立刻向前扑了过去。

• jump

  Jump is the plain, everyday verb for pushing off the ground with the legs; it is neutral in tone and fits ordinary actions like hopping repeatedly or jumping over something.

  jump 是最普通、日常的说法，指用腿蹬地离开地面；语气中性，适用于反复蹦跳或跳过某物等普通动作。

  The kids jumped up and down with excitement when they won the game.

  孩子们赢得比赛后，兴奋地又蹦又跳。

• leap 本词

  Leap emphasizes covering a long distance or reaching a great height in one powerful bound, sounding more dramatic or literary than the plain word jump.

  leap 强调一跃之间跳得很远或跳得很高，动作有力，语气比普通的 jump 更具戏剧性、更书面化。

  The salmon leaped high out of the water to swim upstream.

  那条鲑鱼从水中高高跃起，逆流而上。

All three words mean to jump up suddenly. Spring means a quick, sudden movement. Jump is the plain word for pushing off the ground. Leap means covering great distance or height, sounding dramatic. Not compared: spring's water/coil/season senses, jump's price-rise sense, leap's 'risky attempt' idiom.

这三个词都表示身体突然离地跳起，但侧重点不同：jump 是最普通、日常的说法；spring 强调动作发生得突然、迅速，常带有反应性；leap 则强调跳得远或跳得高，语气更有力、更书面化。这里不比较 spring 的“泉水、弹簧、春天”等义项，也不比较 jump 的“（价格、数量）骤增”义项，以及 leap 的“冒险尝试（leap of faith）”等比喻义。
