1. Indefinite Articles: A and AN

These are used for non-specific, singular, countable nouns.

  • Use “a” before words that start with a consonant sound.

    • Examples: a dog, a car.

• The “H” Rule: Use “an” if the ‘h’ is silent (vowel sound) and “a” if the ‘h’ is pronounced.

  • Examples: an hour, an honest man BUT a horse.

• The “U” and “E” Rule: Words starting with “u” or “eu” often have a “y” sound (/juː/), which is a consonant sound. Use “a”.
