Confusing Words

here vs hear

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

  • here — Here' refers to the place where you currently are or to the location being discussed — for example, Please bring your books here so we can begin the lesson.
  • hear — Hear' is a verb that means to receive sound through your ears — for example, She leaned closer so she could hear the teacher's instructions over the noise.
