Articles: a, an and the
1,350 fill-in-the-gap exercises across 3 forms
The choice is between a, an, the and nothing. It depends on two things: whether the noun can be counted, and whether the reader already knows which one you mean.
Pick a form to practice
Two questions decide it
1. Can you count the noun? One book, two books — countable. Water, advice, money — uncountable, and they have no plural and never take a or an.
2. Does the listener already know which one? If yes, use the. If not, use a or an for a single countable noun, or nothing for plurals and uncountables.
a or an
The choice depends on sound, not spelling:
- a before a consonant sound: a book, a car, a university (/juː/), a European
- an before a vowel sound: an apple, an egg, an hour (silent h), an MP (/em/)
A university and an hour are the pair worth remembering: the first letter is not what matters.
the
Use it when the reader can identify the thing:
- mentioned before: I bought a lamp. The lamp doesn’t work.
- only one of it: the sun, the moon, the government
- made specific by what follows: the man in the gray coat
- superlatives and ordinals: the best, the first
no article at all
This is the option learners forget, because many languages do not have it. Use nothing for:
- general plurals: I like dogs. — dogs in general
- general uncountables: Coffee keeps me awake.
- most names: She lives in Norway and works for Google.
- meals, most transport, some places: after breakfast, by train, at home, at school
Compare at school (as a pupil) with at the school (at that building).
Nouns that are uncountable in English
These catch almost everyone, because they are countable in many other languages:
advice, information, news, furniture, luggage, equipment, research, knowledge, progress, work, money, bread, traffic, weather, homework
None of them takes a, and none has a plural. To count them, add a phrase: a piece of advice, two pieces of furniture, a bit of news.
All forms

Mistakes to avoid
Wrong: I need an advice. correct: I need some advice.
Advice is uncountable, so it cannot take a or an.
Wrong: She is engineer. correct: She is an engineer.
A job title after be takes a or an in English.
Wrong: I have a informations. correct: I have some information.
Information is uncountable and has no plural.
