Definite and Indefinite articles

The English Articles

In English there are three articles: a, an, and the. Articles are used before nouns or noun equivalents and are a type of adjective. The definite article (the) is used before a noun to indicate that the identity of the noun is known to the reader. The indefinite article (a, an) is used before a noun that is general or when its identity is not known.

The English Definite article

The definite article the is the most frequent word in English.

We use the definite article in front of a noun when we believe the listener/reader knows exactly what we are referring to:

  • because there is only one:

The Pope is visiting Russia.
The moon is very bright tonight.
Who is the president of France?

This is why we use the definite article with a superlative adjective:

He is the tallest boy in the class.
It is the oldest building in the town.

  • because there is only one in that context:

We live in a small house next to the church. (= the church in our village)
Dad, can I borrow the car?(= the car that belongs to our family)
When we stayed at my grandmother’s house, we went to the beach every day. (= the beach near my grandmother’s house)
Look at the boy over there. (= the boy I am pointing at)

  • because we have already mentioned it:

A young man got a nasty shock when he tried to rob a jewellery shop in Richmond. The man used a heavy hammer to smash the windows in the shop.

We also use the definite article:

  • to say something about all the things referred to by a noun:

The wolf is not really a dangerous animal. (= Wolves are not really dangerous animals.)
The kangaroo is found only in Australia. (= Kangaroos are found only in Australia.)
The heart pumps blood around the body. (= Hearts pump blood around bodies.)

We use the definite article in this way to talk about musical instruments:

Joe plays the piano really well.
She is learning the guitar.

  • to refer to a system or service:

How long does it take on the train?
I heard it on the radio.
You should tell the police.

The English Indefinite Articles

We use the indefinite article, a/an, with singular nouns when the listener/reader does not know exactly which one we are referring to:

Police are searching for a 14-year-old girl.

We also use it to show that the person or thing is one of a group:

She is a pupil at London Road School.

Police have been looking for a 14-year-old girl who has been missing since Friday.

Jenny Brown is a pupil at London Road School. She is 1.6 metres tall, with short, blonde hair. When she left home, she was wearing a blue jacket, a blue and white blouse, dark blue jeans and blue shoes. 

Anyone who has information should contact the local police on 0800 349 781.

We do not use an indefinite article with plural nouns or uncount nouns:

She was wearing blue shoes. (plural noun)
She has short, blonde hair. (uncount noun)


We use a before a consonant sound:

a banana (starts with /b/)a university (starts with /j/)

and an before a vowel sound:

an orange (starts with /o/)an hour (starts with /au/)

Note that the choice of a or an depends on sound, not spelling.

Here are 3 activities to learn and practice the English articles

Indefinite Articles Game

Ask students to imagine they are in someone’s house (it could be anyone’s house: the teacher’s, one of the student’s, the house of a famous person well known to the students, etc).
Ask the students what they can see, allowing them to identify anything they like.

Here is an example of how the game can be run:
Student 1:
In Mike’s house I can see a table.
Student 2:
In Mike’s house I can see a table and an apple.
Student 3:
In Mike’s house I can see a table, an apple and a spoon.
Student 4:
In Mike’s house I can see a table, an apple, a spoon and an umbrella.

To stay in the game, students need to remember what has been identified by previous students and use the correct indefinite article for each noun mentioned.

Articles: a(n)/the/zero

This game is called “talented animals” and is designed to help students apply a range of articles correctly to specific common lexical categories.
Students are going to create their own “talented” animals that can play a musical instrument and play a kind of sport. These categories open the way for application of the indefinite (a/an) article, the definite (the)
article, and the zero article.
The activity begins with the teacher ruling off three columns on the whiteboard. In the first column, the class brainstorms a list of animals. In the second column they choose a list of musical instruments. In the third column the class selects a variety of different sports. Once these three lists have been filled out, the teacher indicates that the first column with require “a” or “an”, the second column requires “the” and the third column requires nothing (i.e., neither “a/an” or “the”.

Students then set out to create their “talented animals”, which they describe for the class:
Student 1:
My talented animal is a tiger. It can play the guitar and it can play soccer.
Student 2:
My talented animal is a lizard. It can play the trumpet and it can play
basketball.
Student 3:
My talented animal is an elephant. It can play the violin and it can play
baseball.
Student 4:
My talented animal is an ant. It can play the drums and it can play
badminton.

Once students become accustomed to this pattern, other descriptive categories can be added which also apply articles in regular and specific ways. For example, the students can be required to indicate how often the animals practice their instruments and sports
(requiring an indefinite article, as in “twice a week” or “five times a day”), what countries the animals come from (requiring a zero article except in cases such as “The United States”), what time they eat breakfast, lunch and dinner (zero article), and what school
subjects they are good at (also zero article).
