Articles: A, An & The
July 22, 2025
Posted by STLCC in Writing Resources
Every time you use a noun, you must decide if you need to put an article in front of it or not. These tiny words — a, an, and the — don’t even exist in many other languages, so they can cause plenty of trouble for non-native students. In addition, some nouns don’t need articles while other similar nouns do need articles.
Indefinite Articles
The articles a and an are called indefinite articles because they refer to one non-specific person, place, thing, or idea.
Use a before words that begin with a consonant sound:
- a book
- a teacher
- a university
Use an before words that begin with a vowel sound:
- an apple
- an idea
- an honor
Remember that the sound of the word matters, not just the first letter. The h in honor is silent, so the word begins with a vowel sound. That is why we say an honor instead of a honor.
Example sentences:
- I saw a good movie last night.
- I fried an egg this morning.
- I have an hour to study before the test.
- I want a home in the countryside.
Definite Articles
The article the is called a definite article because it refers to a specific person, place, thing, or idea. It can be used with both singular and plural nouns.
Examples:
- the sun
- the stars
- the student center
Example sentence:
- I hope the stars appear in the sky tonight.
Other Options
Sometimes, a singular noun does not need an article when it refers to something specific that cannot be confused with anything else. For example, we do not usually use an article before names of places or concepts such as America or gravity.
Sometimes, the word some can be used as an article when referring to an unspecified amount or number.
- some news
- some surprises
- some medicine
In other cases, a noun can be used with or without an article without changing the meaning of the sentence.
Examples:
- In the winter, the weeds still grow.
- In winter, weeds still grow.
Choose for Clarity
Finally, the following sample shows the different meanings a sentence can have depending on which article is used.
Examples:
I am invited to:
- a party. (This means you probably don’t know about this party.)
- the party. (This means you probably know about this party.)
- parties. (This means I often get invited to various parties.)
