Detailed Summary
Indefinite Articles 'a'/'an'
Indefinite articles 'a' and 'an' are used to refer to non-specific or general nouns. They are used only with singular countable nouns.
Topics Covered:
- Usage of 'a': Used before words that begin with a consonant sound.
- Examples: 'a book', 'a cat', 'a university' (starts with a 'y' sound, which is a consonant sound), 'a one-way street' (starts with a 'w' sound, which is a consonant sound).
- Usage of 'an': Used before words that begin with a vowel sound.
- Examples: 'an apple', 'an elephant', 'an hour' (the 'h' is silent, so it starts with an 'o' vowel sound), 'an honest person' (the 'h' is silent, so it starts with an 'o' vowel sound).
- Focus on Sound, Not Letter: The key distinction is the sound at the beginning of the word, not necessarily the first letter.
