Articles
When to use a, an, the, or no article at all.
Articles are small words that go in front of nouns to show whether we mean something general or something specific. English has three articles: the indefinite articles "a" and "an", and the definite article "the"; sometimes we use no article at all, which is called the zero article. We use "a" or "an" with a single countable noun that is not specific, and the choice depends on the SOUND that follows, not the spelling: "a" comes before a consonant sound and "an" before a vowel sound. We use "the" when both the speaker and listener know exactly which thing is meant, or when there is only one of it. We use no article with general plurals, uncountable nouns, most country names, languages, meals, and many fixed expressions. The article we choose can completely change the meaning of a sentence. For example: "I want a book" means any book, while "I want the book" means one particular book we both have in mind.
Key terms

|---|---|---|
| a / an | Singular countable noun, not specific, often first mention | I saw an elephant; She bought a book |
| the | Something specific, already known, or unique | Look at the sun; The pen was cheap |
| zero (no article) | General plurals, uncountables, most proper nouns | Cats are clever; Water is essential; They travel to Azerbaijan |
| Word | First sound | Article |
|---|---|---|
| university | consonant sound /j/ (like "you") | a university |
| European | consonant sound /j/ (like "you") | a European |
| one-way street | consonant sound /w/ (like "wun") | a one-way street |

- 1Sentence: I bought a pen and a notebook. ___ pen was cheap, but ___ notebook was expensive.
- 2First mention: The pen and notebook are introduced for the first time, so they take "a".
- 3Now known: On the second mention both items are specific and known to us, so they switch to "the".
- 4Answer: The pen was cheap, but the notebook was expensive.
- 1Sentence: He studies at ___ university in London.
- 2Check the sound: "University" begins with the consonant sound /j/ (like "you"), not a vowel sound, even though it is spelled with a "u".
- 3Apply the rule: A consonant sound takes "a", not "an"; the noun is singular, countable and not specific.
- 4Answer: He studies at a university in London.
Do not choose the article by the first letter. Judge by the first SOUND: "a university" and "a one-way street" (consonant sounds), but "an hour" and "an MP" (vowel sounds).
Do not put "the" in front of general uncountable nouns. Say "Honesty is an important quality", not "The honesty..."; "the" would make it a specific honesty.
Unique things and superlatives and ordinals always take "the", even on first mention: the sun, the moon, the best student, the first person. Never "a sun" or "a best".
Learn fixed phrases as whole units with their set article: "the same", "by car", "on foot", "go to school", "go to bed", "go home" (no "to", no "the"), and "have breakfast" (no article).
Rules
- 1Use "a" before a consonant SOUND and "an" before a vowel SOUND — judge by sound, not spelling: a university (/juː/), a one-way street (/w/), an hour (silent h), an MP (/em/).
- 2Use "a" or "an" only with singular countable nouns that are not specific; never with plurals or uncountable nouns (a chair, but NOT a water).
- 3Use "the" for something specific or already known, for things that are unique (the sun, the moon), with superlatives and ordinals (the best, the first), and with rivers, seas and oceans (the Nile, the Pacific).
- 4Use no article (zero article) for general plurals and uncountable nouns (Cats are clever; Water is essential), most countries (Azerbaijan), languages (English), meals (breakfast), and sports.
- 5Many fixed expressions take a set article: "the same", "by car", "on foot", "go to school", "go home" — learn these as whole phrases.
