Rules for using articles a, an, the correctly

Master English: Avoid Common Grammar Mistakes!: Rules for using articles a, an, the correctly

The rules for using articles “a,” “an,” and “the” correctly in English are as follows:

Use “a” before words that begin with a consonant sound. Example: a car, a university (because it starts with a “yoo” sound).
Use “an” before words that begin with a vowel sound. Example: an apple, an hour (because the “h” is silent and it starts with a vowel sound).
Use “a” or “an” with singular, countable nouns that are non-specific or when mentioning something for the first time.
Examples:
- I saw a bird in the garden. (any bird, not specific)
- He needs an umbrella. (any umbrella, not specific)

Use “the” when referring to a specific noun that is already known to the listener or reader or is unique.
Use “the” for specific things mentioned before or known by context.
Examples:
- The sun rises in the east. (unique)
- I saw a dog. The dog was barking loudly. (specific dog already mentioned)
Use “the” with superlatives (the best), ordinal numbers (the first), unique objects (the moon, the internet), geographical features (the Amazon River, the United Kingdom), and collective or specific groups (the Smiths as a family).

No article is usually needed with plural nouns when speaking generally:
- Dogs are friendly.
No article with uncountable nouns when talking generally:
- I like milk.
Use “the” with uncountable nouns when specifying something particular:
- The milk in the fridge is sour.

an	Before vowel sounds, singular, non-specific nouns	an apple, an hour

These rules cover the basic and most common uses of English articles, helping to convey specificity and clarity in communication.
