Articles in English Grammar: A, An, and The – Explained Simply
Sometimes you’re talking about any thing. Other times, it’s something specific. That’s where articles help! These tiny words—a, an, and the—do some mighty work in English grammar.
What Are Articles in English Grammar?
Articles are words we use before nouns (a person, place, thing, or idea) to show whether we’re talking about something specific or general.
There are two types:
Indefinite Articles: a and an
Definite Article: the
Indefinite Articles: “A” and “An”
‘A’ and ‘an’ are indefinite articles. We usually use a/an with a noun to talk about a person or thing for the first time.
- We use a/an with a singular noun.
- We use ‘an’ with a noun beginning with a vowel or vowel sound (a, e, i, o, u).
Examples: an apple, an orange, an umbrella, an identity card.
The article ‘an’ is also used before an adjective or noun if they have a vowel sound.
Examples: an hour, an NCC officer, an MLA, a European, a union.

Use the definite article ‘the’ with any noun (whether singular or plural, count or non-countable) when the specific identity of the noun is known to the reader, as in the following situations.
Use ‘the’ article when a particular noun has already been mentioned previously.

Additional information regarding the use of Articles in English
For the purposes of understanding how articles are used, it is important to know that nouns can be either countable (can be counted) or non-countable (indefinite in quantity and cannot be counted). In addition, countable nouns are either singular (one) or plural (more than one). Non-countable nouns are always in singular form.
When indicating an unspecified, limited amount of a countable or non–countable noun, use some.
My cousin was seeking some advice from a counsellor. (Not advice in general or advice about everything, but a limited amount.)
I would love some coffee right now. (Not coffee in general, but a limited amount of coffee.)
We might get rain tomorrow. Some rain would be good for the crops. (A certain amount of rain, as opposed to rain in general.)
There are some drops of water on the table. (A limited number, but more than one drop.)
Non-countable nouns are those which usually cannot be counted. Following are some common examples:
Certain food and drink items:
butter, cabbage, candy, cauliflower, celery, cereal, cheese, chicken, chocolate, coffee, corn, cream, fish, flour, fruit, ice cream, lettuce, meat, milk, oil, pasta, rice, salt, spinach, sugar, tea, water, wine, yogurt
Certain non-food substances:
air, cement, coal, dirt, gasoline, gold, paper, petroleum, plastic, rain, silver, snow, soap, steel, wood, wool
