ESL Articles Exercises: A, An, The & No Article
Choose an article by meaning, countability and sound. Use a/an with a singular countable noun when the reader does not know which one you mean. Use the when the reader can identify it. General plural and uncountable nouns often need no article: Owls hunt. Information helps. Choose a or an by the next sound: a university, but an hour.
Try the eight questions, explain your choices, then use the same distinctions in a short museum report. All activities and answer keys below are free to read without an account.
A, an, the or no article: a quick chart
| Choice | What to check | Example |
|---|---|---|
| A | One singular countable item; next sound is a consonant. | We need a small box. |
| An | Same meaning as a; next sound is a vowel. | We need an empty box. |
| The | The reader can identify which item, group or material you mean. | Use the box beside you. |
| No article (Ø) | A plural or uncountable noun used generally. | Boxes take up space. Cardboard can be recycled. |
Read the whole noun phrase. An adjective can change the next sound: a box becomes an empty box. A possessive or demonstrative can already do the determiner's job: write my notebook or this notebook, without adding an article before it.
Context matters: I need a key can introduce an unspecified key; I need the key assumes an identifiable one. First mention does not always mean a/an: you can say Please close the door if both people know which door. The exercises state the intended meaning where this distinction affects the answer.
Eight articles exercises with explained answers
Write a, an, the or Ø (no article) in each gap. Follow the stated context. Try a question before opening its answer.

1. Introducing something new
You are telling a friend about one owl they have not heard about before: I saw ___ owl for the first time yesterday.
Answer 1 and explanation
An owl. You are introducing one singular countable animal, and owl begins with a vowel sound. The owl would imply that the listener could identify which owl you meant.
2. A vowel letter, a consonant sound
Describe her status without identifying her as a particular previously mentioned student: She is ___ university student.
Answer 2 and explanation
A university student. University starts with the /j/ sound heard at the beginning of yes. The written letter u does not make an correct here.
3. A silent letter
Say that the wait lasted one hour: We waited for ___ hour.
Answer 3 and explanation
An hour. The h is silent, so the word starts with a vowel sound. Here the noun phrase expresses the length of the wait.
4. Referring back
I bought a red notebook and a blue notebook. ___ red notebook is for English.
Answer 4 and explanation
The red notebook. The first sentence has introduced it, and the colour identifies which of the two notebooks you mean.
5. A general plural
Make a statement about cats as a kind of animal, not a particular group: In general, ___ cats sleep a lot.
Answer 5 and explanation
No article: In general, cats sleep a lot. The cats would refer to an identifiable group. Neither a nor an can directly determine this plural noun.
6. Specific uncountable information
Refer to the particular information in yesterday's message, which both people know about: ___ information you sent yesterday was useful.
Answer 6 and explanation
The information. Information is uncountable in this use, but the message makes it identifiable. Uncountable does not mean “never use the.”
7. A general uncountable noun
Discuss information in general, with no particular message in mind: Accurate decisions depend on ___ information.
Answer 7 and explanation
No article: depend on information. For one individual item, change the noun phrase to a piece of information. Do not write an information in this sense.
8. A possessive is already present
Choose only an article or no article; keep my: I left ___ my notebook at home.
Answer 8 and explanation
No article: I left my notebook at home. The possessive determiner my already specifies the noun. Do not combine it with a, an or the in this position.
Use the choices in a museum report
A visitor is describing a museum visit to a friend who was not there. Introduce one previously unknown old camera, then refer to that same camera. Introduce an empty frame your friend does not know about. The last sentence describes photographs in general.
Yesterday I saw ___ old camera in a museum. ___ camera belonged to a local photographer. It was displayed beside ___ empty frame. In general, ___ photographs can preserve family memories.
Complete the four gaps. Then add two sentences about one imaginary object: introduce it, and say something else about that same object. Underline both noun phrases and explain the change in article.
Museum-report key and a model extension
An; the; an; no article. An old camera introduces the object; the next sound is the vowel at the start of old. The camera refers back to it. An empty frame introduces another object, with a vowel sound after the article. The final sentence refers to photographs generally.
One possible extension: “I also saw a silver watch. The watch had a cracked face.” Other objects and details are possible. Check that the second sentence clearly refers to the first sentence's object; do not mark every difference from the model as an error.
Choose follow-up by the reason for the error
- Questions 2 or 3: ask the learner to say the next word aloud. Compare a consonant sound with a vowel sound before adding more written gaps.
- Questions 4 or 6: ask “How does the reader know which one?” Let the learner point to the earlier sentence or identifying phrase.
- Questions 5 or 7: contrast a general statement with a sentence about an identifiable group or message.
- Question 8: check the whole noun phrase for a possessive or demonstrative before choosing an article.
The pattern of responses suggests what to practise next; this short activity is not a proficiency test. Ask learners to explain an answer and produce a new example before deciding that a rule is secure.
Optional practice on The Kingdom of English
For platform work, check the current topic selection and follow the grammar assignment walkthrough. Grammar activities check typed responses against stored answers. The public questions on this page are separate teaching materials; the assignment workflow does not import this worksheet.
The teacher progress guide explains assignment completion and grammar high scores, attempts and success percentages. Those records do not establish why an article was chosen or whether it transfers to new writing. Use the museum report above for that follow-up. Longer platform writing has a separate workflow described in the writing-practice guide.
