Articles (A, An, The) define whether a noun is specific or unspecific. The biggest mistake learners make is focusing on spelling rather than sound!
Sound Determines 'A' vs 'An'
Use AN before vowel sounds (A, E, I, O, U sounds). Use A before consonant sounds.
An hour: Starts with silent 'h', sounds like 'our' (vowel sound).
An honest officer: Silent 'h'.
A university: Starts with 'u', but pronounced 'yoo' (consonant sound).
A European country: Pronounced 'yoo-ro-pean'.
When to Use Definite Article 'THE'
- Unique entities: The Sun, the Moon, the President.
- Rivers, seas, oceans, mountain ranges: The Ganges, the Pacific, the Himalayas.
- Superlatives: The tallest building, the best score.
- Countries with plural names or political words: The United States, the Netherlands (but India, France with no article).
