A vs. An: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 26, 2023
"A" and "an" are indefinite articles, with "a" used before consonant sounds and "an" before vowel sounds.
Key Differences
"A" and "an" are both indefinite articles in English, signifying a non-specific item or quantity. While "a" is used in front of words that begin with a consonant sound, "an" is placed before words that start with a vowel sound.

Consider pronunciation when choosing between "a" and "an." It's the sound that determines the correct article, not necessarily the letter. For instance, "a user" is correct because "user" starts with a "y" sound, a consonant. On the other hand, "an hour" is correct as "hour" begins with a silent "h" and an "ow" sound, a vowel.

Both "a" and "an" help to introduce something not previously known to the listener or reader. When mentioning something for the first time, we might say "a book" or "an apple." Once it's known, specific articles like "the" might be used.

It's essential to remember that "a" and "an" are used with singular nouns. If speaking about one non-specific cat, we'd say "a cat." For one non-specific egg, it would be "an egg."
