Articles: a, an & the.
Three little words — a, an, the — and the choice between them is mostly about two questions: is it specific, and does it start with a vowel sound?
“a” vs “an” — listen, don’t look
Use an before a vowel sound, and a before a consonant sound. The trick: it’s the sound, not the letter.
Both a and an are the indefinite article: one of many, not yet specific. “I need a pen” — any pen.
“the” — the specific one
Use the when the listener knows exactly which one you mean: it was mentioned before, it’s unique, or it’s clear from context.
- Unique things: the sun, the internet, the President.
- Superlatives: the best, the first, the only.
- Shared context: “Close the door.” (we both know which door).
When to use no article at all
Drop the article for plurals and uncountables when you mean them in general, and for most names.
“I have a information” → some information. Uncountable nouns take no “a/an”.
