Articles signal whether a noun is specific or general. English has three articles — a, an, and the — each with distinct rules that even advanced learners sometimes mix up.

A & An — Indefinite Articles
Use a or an before singular countable nouns when referring to something for the first time or something non-specific. Use a before consonant sounds (a book, a university) and an before vowel sounds (an apple, an hour). Note: it is the sound, not the letter, that decides which to use.
The — Definite Article
Use the when both the speaker and listener know which specific thing is being referred to. This happens on second mention (I have a cat. The cat is friendly.), when there is only one of something (the sun, the president), with superlatives (the best), and with certain places by convention (the gym, the supermarket, the sea).
When to Use No Article
Do not use an article before plural or uncountable nouns used in a general sense (Dogs are loyal. Water is essential.), before most proper nouns (She lives in France.), before languages, sports, and academic subjects (He studies chemistry. She plays tennis.), and before meals (We had breakfast at 8.).
Tricky Article Choices
Some words are tricky because their first letter does not match their first sound (a university — "you" sound; an honest person — silent H). Others can be tricky with specific phrases: in American English, "in the hospital" means someone is a patient, while "at the hospital" can mean visiting. Practice these with extra care.
