Confusing Words

sea vs see

These two words sound exactly the same but have very different meanings.

  • sea — Sea' is a noun that refers to the large body of salt water that covers much of the earth's surface — for example, The research vessel sailed into the open sea to collect water samples.
  • see — See' is a verb that means to perceive something with your eyes — for example, She climbed the hill so she could see the entire coastline from above.

Memory rule: A helpful trick: 'sea' contains the letters 's', 'e', 'a' — think of salt, endless, aqua to remind you it refers to water. If you are describing the act of looking, use 'see'.
