Compared meaning: a small area of still water (noun).

比较义项：小片静水（名词）。

• pool

  Pool suggests a still body of water deep enough to wade or swim in, such as a natural pool among rocks or in a stream, not just rainwater on the ground.

  pool 指足够深、可以涉水或游泳的一小片静水，比如岩石间或溪流中的天然水塘，而不仅仅是地面上的雨水。

  The kids swam in the pool all afternoon in summer.

  孩子们整个夏天下午都在水塘里游泳。

• puddle 本词

  Puddle names a shallow patch of water, usually rain lying on a road or pavement, too small to swim in and often something children jump or splash in.

  puddle 指浅浅的一小片积水，通常是雨后留在道路或人行道上的，浅到无法游泳，常常是孩子们跳进去玩耍的地方。

  The children jumped happily in every puddle after the storm.

  暴风雨过后，孩子们高兴地跳进每一个小水坑里。

Pool and puddle both mean a small area of still water. Pool suggests water deep enough to wade or swim in. Puddle means a shallow patch of rainwater on the ground, too small to swim in. Pool's other meaning, a swimming pool, is not compared.

这两个词都指自然形成的一小片静水，但深浅和用途不同：pool 通常更深，可以供人涉水或游泳；puddle 则很浅，多是雨后地面积水，只能踩踏或跳跃，不能游泳。这里不比较 pool 的其他义项，例如“游泳池”或“资金池”。
