KK.1 Learn how to use the articles "a" and "an"

Loading questions...

What are articles?

Articles are special words used before nouns. They help us understand whether we are talking about something specific or general.

Examples:
  • I saw a dog in the park. (any dog, not specific)
  • She has an apple for lunch. (any apple, not specific)
Note

In English, the articles “a” and “an” are used with singular nouns to mean one of something, not a specific one.

When to use "a"

Use “a” before words that begin with a consonant sound.

Examples:
  • a book
  • a pencil
  • a teacher
Note

Remember, it’s about the sound, not just the letter. For example: “a university” (the “u” sounds like “yoo,” a consonant sound).

When to use "an"

Use “an” before words that begin with a vowel sound (a, e, i, o, u).

Examples:
  • an apple
  • an elephant
  • an hour (the “h” is silent, so it starts with a vowel sound)
Note

Pay attention to the sound at the beginning of the word, not only the letter. For example: “an honor” (silent “h”).

Using "a" and "an" in sentences

Practice using “a” and “an” correctly in full sentences to show you understand the rule.

Examples:
  • She wants to buy a car.
  • I need an eraser for my test.
  • We saw a horse and an owl at the farm.
Note

If you can say the sentence out loud and it sounds natural, you are probably using the correct article.

Common mistakes with "a" and "an"

Sometimes students mix up articles when a word starts with a tricky sound. Focus on the pronunciation, not just the spelling.

Watch out for:
  • Correct: a unicorn (sounds like “yoo-nicorn”)
  • Correct: an umbrella (starts with a vowel sound)
  • Incorrect: a apple (should be “an apple”)
Note

Always say the word aloud in your head. Ask yourself: does it begin with a vowel sound or a consonant sound?
