Articles: a, an, the

When to use a, an, the, or nothing at all.

The rules

  • Use "an" before a vowel sound: "an engineer", "an hour".
  • First mention takes "a" (new information); second mention takes "the" (now we both know which film).
  • General, uncountable concepts take no article: "I love music", "Life is short".
  • Instruments take "the" ("play the guitar"); sports take no article ("play tennis").
  • "An" comes before the adjective when the adjective starts with a vowel sound.
  • Individual mountains take no article, but superlatives always take "the": "the highest".

Examples

  • She is an engineer at a software company.
  • I saw a film yesterday. The film was fantastic.
  • I love music.
  • He plays the guitar and his sister plays tennis.
  • This is an interesting book.
  • Mount Everest is the highest mountain.
