The word "uniform" starts with a consonant sound, even though the letter "u" is a vowel. This is why we use the indefinite article "a" before "uniform."
Here's a breakdown:
- Consonant Sound: The "u" in "uniform" is pronounced like the "y" in "you." It makes a consonant sound, not a vowel sound.
- Indefinite Articles: The indefinite articles "a" and "an" are used before singular nouns. We use "a" before words that start with a consonant sound and "an" before words that start with a vowel sound.
Examples:
- a uniform
- a cat
- an apple
- an hour
In summary, we use "a" before "uniform" because it starts with a consonant sound.
