spring

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

比较义项：突然跳起，跃起（动词）。

• spring 本词

  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

  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。
