Grammar Essentials: Articles (a / an / the)

• a/an = one, non-specific, first mention: I bought a book.
• the = specific/known/unique/second mention: The book I mentioned is here.
• Ø (no article) = in general (uncountable/plural): People need water. / Books are expensive.

Mindset: Ask, “Can the listener identify the exact thing?” If yes → the. If no → a/an. If you mean things in general → Ø.

Using a vs an (sound, not spelling)

• Use an before a vowel sound: an hour, an MBA (em-bee-ay), an umbrella.
• Use a before a consonant sound: a university (you-), a one-way ticket (w-).

First vs second mention

• First mention: I saw a film yesterday.
• Second mention: The film was inspiring.

Specific vs general

• Specific: Close the window (we both know which one).
• General (uncountable/plural): Milk is healthy. / Bicycles reduce traffic.

Tip: With uncountables, add a partitive if you mean one unit: a glass of water, a piece of advice.

Unique/only one → the

• the sun, the sky, the government, the internet, the Prime Minister
• Superlatives/ordinals: the best, the first, the second chart

Generic classes

• Plural/uncountable (preferred): Doctors need training. Plastic harms oceans.
• Singular with the (formal/academic): The tiger is an endangered species.
• Singular with a (one example): A tiger is a big cat.

Places & names (common patterns)

• No article: continents, countries, cities, streets, lakes, mountains → Bangladesh, Dhaka, Lake Victoria.
• Use “the”: country names with republic/kingdom/states, plural countries, rivers/seas/oceans/deserts, groups of islands, ranges → the United Kingdom, the Netherlands, the Nile, the Pacific, the Sahara, the Maldives, the Himalayas.
• Buildings/institutions: go to school/prison/hospital (Ø when used for their main purpose); visit the school (as a building).

Noun + of + noun

• If the first noun is specific/defined → the: the center of the city, the top of the page.
• Set phrases may take Ø: at home, by car.

Adjectives with nouns

• The article depends on the noun, not the adjective: a difficult question, the main reason.

Countable vs uncountable quick test

• If you can say “one/two ___,” it’s countable → might need a/the.
• If not, it’s uncountable → usually Ø for general meaning (advice, information, traffic, research).
