Articles exercises with answers: Choose A An The
How do I choose between a, an, the, and no article?
Articles signal whether a noun refers to a general concept, an unidentified single item, or an item that the listener can identify. The indefinite articles a and an introduce one singular countable noun whose exact identity is not yet shared or important. The definite article the points to an identifiable noun, whether singular, plural, or uncountable.
Pontos principais
- When you discuss plural categories or uncountable substances in general, English leaves out the article entirely.
- Check for existing determiners first, then check whether the listener can identify the noun.
- Use the for identifiable nouns of any number or countability.

Exemplos

The definite article the specifies the exact projector identified by its clear physical location.
-
Safety goggles protect eyes from flying dust during woodworking.

Ask for Any Chair or Identify the Chair You Need
Articles are short words that appear before nouns or before an adjective followed by a noun. When you help organize a community workshop, your article choice changes what the listener looks for. Asking for a chair tells a partner that any seat works fine. Asking for the chair points to one particular seat you both recognize. In everyday conversations, this distinction helps everyone find the right items quickly.
Sometimes a sentence needs no article at all. Choosing no article means leaving the space completely empty when you speak or write. In grammar exercises and answer keys, you often see the symbol Ø to mark this choice. Remember that Ø is merely an exercise label for your study notes, never a real word or symbol to include in ordinary English sentences.
-
Please bring a chair from the hallway so we can start setting up.
Por que funciona: A chair means any suitable chair because any seat from the hallway will work.
-
Please bring the chair beside the entrance into this circle.
Por que funciona: The chair identifies one exact seat based on its clear physical location.
-
Volunteers arranged chairs in five straight rows before the meeting.
Por que funciona: No article is used before the plural noun chairs because it describes seats without pointing to a unique set.
Sua vez
A volunteer asks: 'Can you grab ___ chair near the projector?' There is only one projector in the room. Which article fits?
Resposta: the
Mostrar a resposta
Resposta: the
The specific location near the projector identifies the exact chair that the speaker wants.
Check Whether the Noun Is Countable in This Meaning
Before selecting an article, check what kind of noun you have. Countable nouns name items you can count as units, such as one chair or two chairs. Uncountable nouns name materials, liquids, or collective resources that cannot be counted individually, such as equipment or water. Countability depends on the noun's meaning in that sentence, not whether real objects can physically be counted. Singular countable common nouns normally need an article or another determiner in ordinary sentences.
-
Every table needs a pen and two notebooks for today's notes.
Por que funciona: Pen and notebook are countable nouns shown as one unit and multiple units.
-
We stored audio equipment in the locked cabinet behind the stage.
Por que funciona: Equipment is an uncountable noun here, so it takes no indefinite article.
-
Cold water is available in the lobby for all attendees.
Por que funciona: Water is uncountable in this sentence, standing alone to name the substance generally.

Which word in a workshop inventory cannot take the indefinite article 'a' directly?
Resposta: equipment
Mostrar a resposta
Resposta: equipment
Equipment is an uncountable noun in English and cannot be counted directly with 'a'.
Use A or An for One Item the Listener Need Not Identify
Use a or an when you refer to one singular countable item whose identity is not shared or not important to the listener. Even if you know the exact item in your own mind, you introduce it with a or an when the listener does not need to identify it yet. This choice signals to your listener that any suitable member of the category works or that its specific identity does not matter for the message.
-
I need a screwdriver to tighten this loose table leg.
Por que funciona: The speaker needs any single screwdriver from the toolkit that can complete the repair.
-
An organizer will arrive early to unlock the front doors.
Por que funciona: The listener only needs to know that one organizer is coming, not their identity.
-
She picked up a folder from the registration counter.
Por que funciona: The sentence reports that one folder was taken without identifying which particular one.
Sua vez
Why does a volunteer say 'We need a microphone' instead of 'the microphone'?
Resposta: Any microphone that works will solve the problem.
Mostrar a resposta
Resposta: Any microphone that works will solve the problem.
Using 'a' shows that the listener does not need to identify a specific, known microphone.
Choose A or An from the Next Word's Sound
Your choice between a and an depends strictly on the spoken sound at the start of the word immediately after the article. Use a before a consonant sound and an before a vowel sound. Letters can mislead you because spelling does not always match pronunciation. We say an umbrella, but a useful tool because useful begins with /j/. We say an hour because the letter h is silent. An adjective can change the sound, as in a large room.
-
We have an hour to arrange eighty folding chairs.
Por que funciona: Hour begins with a silent h and a vowel sound, so it requires an.
-
This diagram offers a useful plan for our seating chart.
Por que funciona: Useful begins with the consonant sound /j/, so it takes a despite the initial letter u.
-
They moved from an empty room into a large room.
Por que funciona: The article switches between an and a based on whether empty or large follows.
Sua vez
Which phrase matches the article to the spoken sound of the immediate next word?
Resposta: a useful checklist
Mostrar a resposta
Resposta: a useful checklist
Useful begins with the consonant sound /j/, so 'a useful checklist' is phonetically correct.
Use The When You Mention the Same Item Again
When you introduce a new singular countable item, you usually introduce it with a or an because your listener does not know which one you mean. Once the item is introduced into the conversation, both of you know exactly which thing is being discussed. In your next sentence, you switch to the definite article the. However, second mention is not an automatic mechanical rule. If you mention another item from the same category, you still use a or an.
-
A visitor left a coat on the bench. The coat has silver buttons.
Por que funciona: Coat is introduced with a, and then becomes the coat because it refers back to that exact garment.
-
We found a projector in the closet, but we still need a spare projector.
Por que funciona: The first item used a, and the second mention uses a because it refers to an additional item.
-
An artist brought a banner this morning. The banner hangs near the stage.
Por que funciona: The banner points back directly to the banner that the artist delivered earlier.
Sua vez
Sentence 1: 'We set up a printer.' Sentence 2: '___ printer needs paper.' Which article fits?
Resposta: The
Mostrar a resposta
Resposta: The
The printer is now identified because it was introduced in the preceding sentence.
Use The When the Situation Already Identifies the Item
You do not need to introduce an item with a or an first if the surrounding situation already identifies it clearly. If there is only one entrance to the workshop hall, you say the entrance on first mention. A descriptive phrase can also pinpoint an item, as in the chair beside the door. However, adding a description does not automatically require the. Saying a chair near the window still means any suitable chair in that area.
-
Please adjust the clock on the back wall before people enter.
Por que funciona: The physical room has only one clock on that wall, making the identity obvious immediately.
-
Grab a chair near the window if you want extra light.
Por que funciona: The phrase near the window narrows the area, but any chair there satisfies the request.
-
The facilitator opened the session with a short safety briefing.
Por que funciona: Both speakers recognize the single facilitator leading the workshop in this room.
Sua vez
There are four white tables in a room. A speaker says: 'Bring me ___ table near the door.' Which fits if any of those two front tables will do?
Resposta: a
Mostrar a resposta
Resposta: a
Because multiple tables sit near the door and any of them is acceptable, 'a' remains correct.
Leave Out Articles with General or Unspecified Plural and Uncountable Nouns
The definite article the works with singular nouns, plural nouns, and uncountable nouns when the listener can identify what is meant. In contrast, bare plurals and uncountable nouns express general or unspecified references. Talking about equipment generally is different from discussing the equipment in the locked cupboard, which refers to a specific collection.
Because a and an mean one, they cannot modify plural or uncountable nouns directly. To refer to a single portion of an uncountable substance, place a countable unit noun in front of it. Expressions like a piece of equipment and a bottle of water allow the indefinite article to describe one countable container or unit.
-
Workshops give community members practical skills for home repairs.
Por que funciona: Workshops and skills are plural nouns used generally, so they take no article.
-
The equipment in the supply room needs regular cleaning.
Por que funciona: The specifies the exact collection of equipment stored in that particular supply room.
-
Each volunteer received a piece of equipment for the painting demonstration.
Por que funciona: A piece creates a singular countable unit from the uncountable noun equipment.
-
Please take a bottle of water from the cooler near the doorway.
Por que funciona: A bottle serves as a countable unit noun, allowing an indefinite article before the uncountable noun water.
Sua vez
Complete the general statement: '___ safety glasses protect eyes during carpentry.'
Resposta: Ø
Mostrar a resposta
Resposta: Ø
No article is used before the plural noun 'safety glasses' because it states a general rule about all glasses.
Check for My, This, or Another Determiner First
A common mistake is combining an article with another determiner before the same noun. Determiners are words that help show which thing or how much of something is meant. Words like my, this, that, some, and each already perform this job. English never places an article and a possessive or demonstrative word together in the same determiner position. Check whether your noun already has a word like my or this before you add an article.
-
She left her jacket on that wooden bench.
Por que funciona: Her and that serve as determiners, so no article can appear before jacket or bench.
-
Some participants asked for extra handouts after the presentation.
Por que funciona: Some acts as a determiner, making an article unnecessary and grammatically incorrect.
-
This schedule outlines every activity planned for Saturday.
Por que funciona: This specifies schedule and every specifies activity, so neither noun accepts an article.
Sua vez
Which sentence correctly avoids stacking determiners?
Resposta: Please bring my notebook.
Mostrar a resposta
Resposta: Please bring my notebook.
Possessive determiners like 'my' fill the determiner slot alone without an article.
Choose Articles for Jobs and Routine Meals
Use a or an when mentioning a person's profession or role, as in she is an electrician or he is a carpenter. General statements about occupations in the plural take no article, such as carpenters build cabinets. Names of routine daily meals like breakfast, lunch, and dinner normally take no article in time phrases like after lunch. However, an adjective or an identified occasion changes the meal pattern, as in we enjoyed a wonderful lunch together.
-
Marcus is an electrician who teaches our wiring basics workshop.
Por que funciona: An electrician uses an indefinite article for a singular person's professional role.
-
We will take a thirty-minute break after lunch.
Por que funciona: Lunch names a routine daily meal, so it takes no article in this time phrase.
-
The community center hosted an excellent dinner for neighborhood leaders.
Por que funciona: Dinner takes an indefinite article because the adjective excellent describes a specific meal event.
Sua vez
A colleague says: 'Sofia is ___ plumber, and we will talk after ___ lunch.' Which pair fits?
Resposta: a / Ø
Mostrar a resposta
Resposta: a / Ø
Singular professions take 'a' or 'an', while routine meals in time phrases take no article.
Follow the Article Decision Table
Deciding on the correct article becomes clear when you ask two questions in order. First, check whether the listener can identify the exact item or whether you are speaking generally. Second, check the noun type: singular countable, plural countable, or uncountable. Use the structured decision guide below to confirm your choice before speaking or writing in daily situations.
| Noun type | Identifiability | Article choice | Short example |
|---|---|---|---|
| Singular countable | Identifiable by listener | the | the blue chair |
| Singular countable | Unidentified or any one (consonant sound) | a | a sturdy table |
| Singular countable | Unidentified or any one (vowel sound) | an | an open box |
| Plural countable | Identifiable by listener | the | the spare chairs |
| Plural countable | General or unspecified | no article | chairs need cleaning |
| Uncountable | Identifiable by listener | the | the paint on the shelf |
| Uncountable | General or unspecified | no article | paint dries quickly |
-
The coordinator inspected the tools before the session began.
Por que funciona: The definite article applies to tools because both speakers know the specific set.
-
Tools require careful maintenance to prevent rust.
Por que funciona: No article is used because tools refers to the entire category in general.
-
We bought an extension cord for the sound system.
Por que funciona: An extension cord introduces one singular countable item starting with a vowel sound.
Sua vez

Resposta: water
Mostrar a resposta
Resposta: water
Uncountable nouns used generally take no article.
Hear Articles in a Community Workshop Dialogue
In natural speech, articles are unstressed function words that reduce into weak phonetic forms. The indefinite article a commonly sounds like /ə/, an commonly sounds like /ən/, and the unstressed definite article the commonly sounds like /ðə/ before consonant sounds and /ði/ before vowel sounds. These pronunciation reductions are natural listening patterns with variation rather than absolute rules. Notice how speakers identify tools, locations, and roles as they prepare the workshop room.
-
Priya: 'Could you pass me a marker from the box, Elena?'
Por que funciona: Priya needs any marker, but specifies the known box on the table.
-
Elena: 'Here is a marker, and here is the schedule for our morning group.'
Por que funciona: A marker provides any one pen, while the schedule refers to the unique official handout.
-
Priya: 'Thank you. Let us place an arrow on the sign near the doorway.'
Por que funciona: An arrow begins with a vowel sound /æ/, and the sign refers to the known board by the door.
Sua vez
In fast conversational speech, how is 'the' typically pronounced before the word 'easel'?
Resposta: With the vowel sound /ði/
Mostrar a resposta
Resposta: With the vowel sound /ði/
Before vowel sounds like the initial sound in 'easel', 'the' is commonly pronounced /ði/.
Choose Articles and Explain the Clues
When deciding between articles in writing, look closely for contextual clues. Check whether a descriptive prepositional phrase makes the noun unique or whether it simply describes a general type. Then verify whether the noun is singular, plural, or uncountable. Explaining your reasoning aloud helps turn grammar rules into reliable habits during practical workshop tasks.
-
We ordered a heater for the workshop because winter mornings get cold.
Por que funciona: A heater introduces one item to solve a problem, while the workshop identifies their specific building.
-
The heater in room four stopped running at noon.
Por que funciona: The heater is identified by the exact room location, distinguishing it from all other heaters.
-
Electric heaters consume substantial energy during winter months.
Por que funciona: No article appears before heaters or energy because both represent general categories.
Sua vez
You and your listener know that the crate contained one projector and no other. Complete: 'We unpacked ___ projector from the central supply crate.'
Resposta: the
Mostrar a resposta
Resposta: the
The shared context lets the listener identify the projector, so the is the appropriate article.
Write Six Short Sentences with Progressive Listening Hints
When transcribing spoken sentences, train your ear to catch unstressed function words attached to following nouns. Listening for articles requires tracking the start of noun phrases rather than waiting for heavy syllable stress. Use progressive hints: first identify the main action and meaning, next identify the noun category, and finally focus on the exact vowel or consonant sound preceding the noun.
-
Volunteers moved benches across the polished floor.
Por que funciona: Listening clue: polished begins with a consonant sound, and the floor is uniquely identified in the room.
-
An apprentice assembled an easel beside the window.
Por que funciona: Listening clue: both apprentice and easel begin with vowel sounds, producing the weak form /ən/.
-
She placed paper and pens on the wooden table.
Por que funciona: Listening clue: paper is uncountable and pens is a plural category, so neither has an article.
-
Please bring a chair from the hallway.
Por que funciona: Listening clue: chair starts with a consonant sound, and any chair satisfies the request.
-
The technician brought a spare cord for the display.
Por que funciona: Listening clue: technician and display are identifiable in this room, while cord introduces one new unit.
-
An organizer placed the new signs near the main entrance.
Por que funciona: Listening clue: organizer starts with a vowel sound, while signs and entrance are specific and known.
Sua vez
When a speaker says /ən ˈaɪtəm/, which written phrase matches the pronunciation?
Resposta: an item
Mostrar a resposta
Resposta: an item
The reduced form /ən/ signals the indefinite article 'an' before the vowel sound in 'item'.
Repair Article Mistakes and Rebuild the Scene from Memory
To consolidate your skills, review written sentences and repair common article errors. Look for singular countable nouns standing alone without determiners, unnecessary articles before general plural categories, and mismatched phonetic choices like a before vowel sounds. Reconstructing a workshop scene from memory helps you practice balancing shared context against general facts in natural writing.
-
Correction: 'He brought an umbrella and a ladder to the worksite.'
Por que funciona: Corrected from 'a umbrella' and isolated 'ladder', matching vowel sound and singular countable requirements.
-
Correction: 'Furniture needs dusting before participants enter the hall.'
Por que funciona: Corrected from 'The furniture' or 'A furniture' when making a general statement about workshop maintenance.
-
Correction: 'We reviewed the plans with an experienced builder.'
Por que funciona: Corrected to use the for the shared plans and an before the vowel sound in experienced.

Perguntas sobre "Articles exercises with answers: Choose A An The"
How do I choose between a, an, the, and no article?
First, check whether your listener can identify the specific item. If the item is identifiable through shared context or description, use the. If it is one unidentified countable item, choose a before consonant sounds or an before vowel sounds. If you are speaking about plural items or uncountable substances in general, use no article.
Please bring a chair from the hallway.
Please bring the chair beside the door.
Chairs provide seating for our guests.
Why is it a useful tool but an hour?
Article choice depends on the spoken sound that immediately follows the article, not the written letter. The word useful begins with the consonant sound /j/, so it takes a. The word hour begins with a silent h followed by the vowel sound /aʊ/, so it takes an.
A useful checklist helps us organize the room quickly.
We finished the preparations an hour before the guests arrived.
Can I use the the first time I mention something?
Yes. You can use the on first mention whenever your physical surroundings, shared knowledge, or a descriptive phrase make the item uniquely identifiable. If there is only one projector in the room, both speakers know which one is meant, so introducing it with the is entirely natural.
Could you turn on the projector near the stage?
The entrance to the building is locked after eight.
Do plural nouns always have no article?
No. Plural nouns take no article when you speak about things in general or when you refer to an unspecified group. However, plural nouns take the definite article the whenever you refer to a specific, identifiable group that both you and the listener recognize.
Volunteers moved chairs into the classroom.
The chairs in the front row are reserved for presenters.
Why can I say equipment but not an equipment?
Equipment is an uncountable noun in English. The articles a and an originally mean one, so they only attach directly to singular countable nouns. To express a single item from an uncountable category, you must add a countable unit noun, such as a piece of equipment.
We stored heavy equipment in the warehouse.
Each volunteer carries a piece of safety equipment.
How can I hear articles when people speak quickly?
Articles are unstressed function words that reduce into quick, weak sounds. Speakers pronounce a as /ə/, an as /ən/, and the as /ðə/ or /ði/. Instead of listening for a separate loud word, listen for the short sound attached directly to the start of the following noun.
He grabbed a brush from the table.
She placed an outline near the door.
Antes de ir
Lembre-se disto
Check for existing determiners first, then check whether the listener can identify the noun. Use the for identifiable nouns of any number or countability. For unidentified items, choose a before consonant sounds and an before vowel sounds with singular countable nouns. Leave out articles for general plural and uncountable nouns.
