Indefinite articles are a confusing concept for many English speakers. What is the best way to remember whether to use “a” or “an” when there are so many rules?

Fortunately, there is a simple trick that can help you to choose the correct indefinite article every time.

  • A” is used before words that begin with consonants
  • An” is used before words that begin with vowels.

However, when we use “A” and “An” has nothing to do with the written letters. The most important tip is to pay close attention to how the word sounds. Words beginning with a vowel sound use “An“. If a word starts with a consonant sound use “A“.

Takeaway: Words that have a vowel sound are preceded by An. Words that have a consonant sound are preceded by A.

Rules for A vs. An

How do you know when to use “a” versus “an”? “A” and “an” are two of the most commonly confused words. Follow these guidelines to help you choose the correct indefinite article:

  • Use “A” before words that begin with a consonant sound, regardless of how they’re spelled. For example: “a dog, a cat, a quickly eaten meal.”
  • Use “An” before words that begin with a vowel sound, regardless of how they’re spelled. For example: “an owl, an umbrella, an hour”.

Pay close attention to words that begin with the letter “h”. While “h” is typically a consonant sound, there are some exceptions. In the word hour, the h is silent and is pronounced more like “our”. In this case, the word starts with a consonant that sounds like a vowel!

Takeaway: Focus on how the beginning of a word sounds.

Examples

Here are some examples of using the indefinite article “A“.

  1. A rose by any other name would smell as sweet.
  2. A stitch in time saves nine.
  3. A penny saved is a penny earned.
  4. Let’s go to the mall to buy a sweater.
  5. I would rather drive a car than walk.

Here are some examples of using the indefinite article “An“.

  1. I drove 100 miles in an hour.
  2. Can you grab me an orange?
  3. At the zoo today we saw an orangutang.
  4. Grab me an apple from the pantry.
  5. I took an extra piece of candy from the bowl.

Definite and Indefinite Articles

There are two types of articles:

  • Definite
  • Indefinite

Definite articles indicate that the noun it modifies is specific or known to the listener. For example, if I say “I’m going to the store” you know which store I mean.

On the other hand, the indefinite article is the word “a” or “an,” and it suggests that the noun it modifies is unspecific or unknown. For example, if I say “Can you give me a ride to the airport?” or “Can you call me an Uber to the airport?” you don’t know which airport I’m talking about.

FAQs – “A or An”

Q: Do you say an hour or a hour?

It is correct to say “an hour“. People pronounce hour with a silent h. When a word begins with a vowel sound, an should be used. This same rule applies to spoken and written form.

Q: Is it a hour or an hour in British English?

The correct form is “an hour” in British English. This follows the same rules as American English. The word starts with a vowel sound so we use an. Vowel sounds are always preceded by an.

Q: Why does hour use an?

Hour uses “an” because the h is silent. Hour begins with a vowel sound. Words beginning with consonant sounds use “a” as the indefinite article. For example, “that is a golf club”. Pay close attention to the h sound. If you pronounce the h, then a should be used. For example, “Please give me a handout.”

Q: When to use a or an?

In the English language, the general rule is that “a” goes before when a word begins with consonants and “an” goes before when a word starts with a vowel. More specifically, you must pay close attention to how the word sounds. For example, “An apple” , “A unicorn”, or “A television”. Use this rule to chose the correct indefinite article in your writing.

Q: Is it a unicorn or an?

It is correct to say “a unicorn”. Most people would think the correct form would be an before a vowel. However, unicorn does NOT make a vowel sound so the correct article is a. Unicorn makes a consonant sound. Not many words fall into this category. Even professional teachers can struggle with these rules.

Q: Is it an or a house?

The correct version is “a house“. The general rule in the English language is that a proceeds words starting with h, where there is no silent h. It can be tricky for a non-native English speaker to understand all the rules with indefinite articles.

Q: Is it correct to say a hotel or an hotel?

It is correct to say “a hotel“. Words beginning with h usually use an. However, this rule applies to words that start with silent letters. In this example, the h in hotel is not silent so the correct article to use is a. Study the difference between an indefinite and definite article to improve your writing.

The Bottom Line

English can be tricky. But with a little practice, you’ll be able to use the indefinite articles “a” and “an” like a pro. These tips should help you get started. Remember to listen for the sound of the word and make your decision based on that.
