Lesson 1Beginner

Articles (a / an / the)

What it means

Articles are small words that come before a noun. a / an means "one, any one" – the listener does not know which one yet. the means "the one we both know".

How to make it

a + consonant SOUND → a book, a cat, a university ("u" sounds like "you")
an + vowel SOUND → an apple, an engineer, an hour (the "h" is silent)
the + any noun (singular, plural or uncountable) → the sun, the cats, the water
Plural or uncountable nouns never take a / an → use some: some water, some advice

When to use it

First time you mention something → a/an: I saw a cat in the garden.
Not a specific one, just any one → a/an: Can I borrow a pen?
Jobs → a/an: She is an engineer.
Second time you mention it → the: The cat was black.
The listener knows which one → the: Please close the door.
There is only one → the: The moon is very bright tonight.

Compare

a cat (new information) → the cat (the cat we already talked about)
a book (consonant sound) → an hour (vowel sound – the spelling starts with "h", but the sound does not)
an umbrella (vowel sound) → a university (starts with a "you" sound)

Common mistakes

❌ I am student. → ✅ I am a student. (a singular countable noun needs an article)
❌ I need an advice. → ✅ I need some advice. (advice is uncountable)
❌ a hour → ✅ an hour (choose by sound, not spelling)

💡 Tip: Before a singular countable noun, ask: "Does the listener know which one?" No → a/an. Yes → the.

. .
First mention uses "a cat"; the second mention uses "the cat" because we now know which cat.
💡 a = new information; the = information already shared.
.
"an" before the vowel sound /e/; "a" before "university" because it starts with a /j/ ("you") sound.
💡 Choose a/an by the first SOUND of the word.
.
"the" because there is only one moon.
