Grammar · Sentence structure
Articles (a, an, the)
Formula: a / an (indefinite) · the (definite)
A1
Quick answer
The 4 main uses
1. A / an: indefinite, singular
A before a consonant sound, an before a vowel sound. The sound decides, not the letter: apple starts with the sound /æ/, so you say an apple.
“I have a book and an apple.”
2. The: definite, already known
Use the for a specific thing: you and the listener know which one.
“The book on the table is mine.”
3. No article: things in general
Use no article with plural nouns and uncountable nouns (like coffee or water) when you talk about them in general.
“I like dogs. / I like coffee.”
4. No article: names, languages, days
Use no article before names of people, languages, days of the week and most cities and countries.
“I speak English. I live in France.”
Common mistakes to avoid
An depends on the SOUND, not the letter
Use an before a vowel sound, even when the first letter is a consonant. Examples: an hour (silent h), an MP3 (M sounds like /em/). It also works the other way: a university, because the u sounds like /juː/.
No article for things in general
A common mistake: I like the dogs when you mean dogs in general. With the, the sentence is about specific dogs (these dogs, the dogs next door). For dogs in general, say I like dogs, with no article.
No article before languages
I speak English ✓ / I speak the English ✗. The same is true for most country names (in France, in Spain). A few names take the: the USA, the UK, the Netherlands.

Frequently asked questions
When do you use a, an and the?+
A/an = any one thing, not mentioned before (I saw a dog). The = a specific thing that you both know (The dog is mine). No article = things in general, with plural or uncountable nouns (I like dogs / I like water).
When do you use an instead of a?+
Use a before a consonant sound (a book, a car). Use an before a vowel sound (an apple, an hour). The sound decides, not the letter. In hour, the h is silent. University starts with the sound /juː/, so you say a university.
Do you use the before a language?+
No. Names of languages are proper nouns (names), so they take no article: I speak English, never I speak the English. This is also true when the language is the subject: English is easy. Most country names take no article either (in France, in Spain).
Why do we say I like dogs and not I like the dogs?+
No article = things in general (dogs as a group). With the, you talk about specific dogs that you both know: I like the dogs next door. For a whole group or an idea in general, English uses no article: Dogs are loyal, Music is fun.
Do you use the with countries and cities?+
Usually not: in Paris, in France, in Japan. Some country names take the: the United States, the UK, the Netherlands. These names are plural, or they contain a word like states or kingdom.
