Hello, and welcome back from the long weekend!

Today's LessonCATEGORY: 混同しやすい言葉
WAVE vs. SWELL   波 vs. うねり


  • A wave is a raised mass of water moving across the surface of the ocean. It may be either smooth or breaking.

    A swell is a long, smooth wave in open water.

    Be Careful! When swells begin to curl and break on the shore, we usually call them waves.
  • wave とは、海面を移動する隆起した水の塊、つまり、波のことです。緩やかなものと砕けるもの、いずれの場合にも使います。

    swell とは、外洋で見られる長くて緩やかな波、つまり、うねりのことです。

    注意:swell が、巻き込むように岸に近づいて砕け始めたものは、普通、wave と呼びます。
