From Wikipedia, the free encyclopedia

A sea generally refers to a large body of salt water, but the term is used in other contexts as well. Most commonly, the term refers to a large expanse of saline water connected with an ocean, and is commonly used as a synonym for ocean. It is also used sometimes to describe a large saline lake that lacks a natural outlet, such as the Caspian Sea.

Sea is a big body of water.

  • Alone, alone, all, all alone,
    Alone on a wide wide sea!

  • It keeps eternal whisperings around
    Desolate shores, and with its mighty swell

    Of Hecate leaves them their old shadowy sound.
  • All that is told of the sea has a fabulous sound to an inhabitant of the land, and all its products have a certain fabulous quality, as if they belonged to another planet, from seaweed to a sailor’s yarn, or a fish story. In this element the animal and vegetable kingdoms meet and are strangely mingled.
  • Behold, the sea itself
  • I must down to the seas again, to the lonely sea and the sky,
    And all I ask is a tall ship and a star to steer her by.
