What are articles?

Articles tell us which thing or what kind of thing we mean. English has two: indefinite (a/an) and definite (the).

a / an
One of many — we don't know which one: a cat, an apple
the
The specific one we both know: the cat (our cat), the moon
∅ (zero)
No article for general ideas: I love music. She's from Spain.
Important: Spanish uses articles differently. English uses no article before general uncountable nouns: "I love music" (not "la música").

a / an — indefinite article

Use before consonant sounds / vowel sounds

a
Before consonant sounds: a cat · a book · a university (u = "you")
an
Before vowel sounds: an apple · an umbrella · an hour (h is silent)
✓ Correct
She is a doctor.
I have an idea.
It is a university.
✗ Wrong
She is an doctor.
→ "d" is a consonant
It is an university.
→ sounds like "you"

the — definite article

Use when the listener knows which one

Second mention
I saw a dog. The dog was big.
Unique things
The sun · the moon · the sky
Superlatives
The biggest · the most beautiful
Rivers/seas/deserts
The Amazon · the Pacific · the Sahara
No "the" with: Countries (Spain, NOT the Spain*), languages, meals, sports: "She speaks Spanish", "He plays football".
