How to Use Articles

Colourful beads spell out 'Grammar'

In today’s blog post, we’ll take a look at when to use articles ‘a’, ‘an’ and ‘the’. Don’t forget to download your free articles cheat sheet at the bottom of the blog!


Let’s start with a general rule about when to use the articles ‘a’ and ‘an’. It’s important to know that ‘a’ and ‘an’ respond to the word that comes after it. What this means is:

If the first letter of the word proceeding it makes a vowel-sound – a, e, i, o, u – then you use the article ‘an’.


I saw an elephant.

Can I have an ice cream?

I’ve never eaten an octopus.

If the first letter of the word proceeding it makes a consonant-sound – b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z – then you use the article ‘a’.


I’d like a milkshake.

Could I have a coffee, please?

I would like to buy a kite.

So, we use ‘a’ and ‘an’ depending on the word that immediately follows the article. This may not always be the noun.


Emma is a doctor (noun).

Emma is an enthusiastic (adjective) doctor.


Now, let’s move onto more specific contexts.

We use ‘a/an’ with countable singular nouns to make clear to the reader who/what we are talking about.


Police are searching for a 15-year-old boy.

She is an aunt of mine.

We also use ‘a/an’ to show that they are one person/thing within a group.


He is an Apple employee.

She is a member of the club.

We don’t use ‘a/an’ with uncountable plural nouns.


Can you guess which sentence is correct and which is incorrect?

He was wearing a red socks.

He was wearing red socks.

She was making rice to go with the dinner.

She was making an rice to go with the dinner.

We also use ‘a’ or ‘an’ when we’re trying to explain who someone is or what job they have.


My mother is a professor.

Isabelle is an artist.

We sometimes use ‘a’ or ‘an’ with a singular noun to talk generally about something. We can also use these general statements to talk about all things of the same kind.


A man’s best friend is his dog.

(Meaning: every man’s best friend is his dog.)

A leopard can’t change its spots.

(Meaning: all leopards are incapable of changing their spots.)


We use the article ‘the’ when the person we’re speaking to knows exactly what we are referring to. We do this for the following reasons…

There is only one.


The Pope lives in Rome.

The Queen of England is very old.

We use ‘the’ with a superlative adjective (used to describe an object at the upper or lower limit of quality, for example, the tallest, fastest, slowest, highest, etc)

To show there is only one in that place or in that area.


We live in the house with the blue door.

(Meaning: there is only one house with a blue door.)

(Meaning: there is only one folder on the desk.)

We use ‘the’ with countries that have kingdom, states or republic in the name.

Interview with Alyssa Ordu

Hello, and welcome to the Intrepid English podcast. My name is Lorraine, and today, I have a conversation for you. My friend Alyssa is a Diversity and Inclusion Consultant in London. And when I told Alyssa that we were creating a diversity and inclusion course, in the intrepid English Academy, we had a lovely conversation about why diversity and inclusion are so important. I asked her to join me on this podcast as an expert in this field, to break down these big topics so that our English learners and the listeners of this podcast can understand a little bit about what diversity and inclusion are, why they’re so important, and give you a little bit of language that you can use to increase your awareness and broaden your horizons in these essential areas.
