There is a simple way to know the difference between a an.
The letter a is used before words that begin with consonants. A consonant is every letter that is not a vowel. In other words, any word that begins with a letter that is not a, e, i, o, or u should have “an” before it.
There are two exceptions to this rule.
· When u makes the same sound as the y in you or o
· It makes the same sound as w in won
In both of the previous cases, an should be used rather than a.
Here are some examples:
- a union
- a wonderful day
- a used rag
- a U.S. flag
- a one-eyed dog
An is used before words that begin with, or sound like a vowel. For instance, the letter “a” should go before an unsounded h.
Here are a couple of examples of unsounded h’s.
· He is an honorable man.
· It was an honest mistake.
To recap:
Use “a” before words that begin with a consonant.
Consonants are and letter other than vowels.
Use “an” before words that begin or sound like a vowel.
If you can remember these rules, you should be able to master whether to use a or an.
