A or An Before H: A Guide to English Article Usage

'A' and 'an' are indefinite articles in English, used to refer to a singular, unspecified noun. Their choice depends on the noun's pronunciation, not its spelling. Generally, 'an' is used before a noun starting with a vowel sound, while 'a' is used before a noun starting with a consonant sound.

For example, 'a book', 'a cat', 'a dog', 'a house', 'a tree' all start with consonant sounds and thus use 'a'.

Words like 'an apple', 'an egg', 'an umbrella', 'an orange' begin with vowel sounds, so 'an' is used.

However, some words require careful consideration. For instance, 'university' starts with a consonant sound, so it's 'a university', not 'an university'. Similarly, 'hour' starts with a vowel sound, but its pronunciation is 'au', making it 'a hour' rather than 'an hour'.

Ultimately, choosing between 'a' and 'an' depends on the pronunciation, so listen carefully!
