English Articles: A, An, The, or No Article?

Articles are easier when you think about whether the listener can identify the noun, rather than memorising isolated rules.

A / an: one, but not identified yet

Use a or an with a singular countable noun when you introduce one example and the listener does not yet know which one.

• I spoke to a teacher.
• She bought an umbrella.

Choose a before a consonant sound and an before a vowel sound: a university but an hour.

The: the listener can identify it

Use the when both people can understand which specific thing you mean.

• I spoke to a teacher. The teacher gave me some advice.
• Please close the door.
• The sun is shining.

No article: things in general

Plural countable nouns and uncountable nouns often have no article when you mean the whole idea or category.

• Books can change the way we think.
• English takes regular practice.
• Information is easy to find online.

Answers: a; The; no article; an.

Three-question method: Is the noun singular and countable? Does the listener know which one? If yes, use the; if not, use a/an. For plural or uncountable nouns used generally, no article is often correct.
