A vs. An
A vs. An
- 
    a car
- 
    a movie
- 
    a snake
- 
    a lantern
The only exception to this rule is when an h is unsounded. For example:
- 
    an honest man
- 
    an herbal garden
- 
    an hour
An precedes all words that begin with a vowel. For example:
- 
    an order
- 
    an alligator
- 
    an elephant
- 
    an udder
There are two exceptions to this rule: When a u makes a y sound (as in united), and when a o makes a w sound, as in one. For example:
- 
    a utopia
- 
    a used towel
- 
    a one-star movie
