The, the definite article, is one of the most common, if not the most common, words in English. The identifies a definite or particular noun that has been mentioned earlier. It is not about a noun that has not been mentioned beforehand or a noun that we are unaware of.


  • He watched a movie. The movie was about the death of a ghost.
    (The movie mentioned in the second sentence is clear as it refers to the movie he watched.)
  • I saw an old man with an eagle. The eagle perched on his right shoulder.
    (The second sentence is correct: an eagle becomes the eagle.)
  • I received the letter. The letter is from the former classmate.
    (The first sentence should use a letter, not the letter as no one, except the receiver of the letter, knows which letter is referred to. The second sentence should use a former classmate, not the former classmate because no one else knows which former classmate is referred to.)
