Y. Dil Write "a / an"

Here are the correct articles ("a" or "an") for each word:

• a train
• an e-mail
• a university
• a camp
• an office
• a video
• a quiz
• a cheetah
• a market
• a film
• an artist
• an ambulance
• a microphone
• a chimpanzee
• an orchestra

The general rule is to use "an" before words that begin with a vowel sound (a, e, i, o, u), and "a" before words that begin with a consonant sound. It's important to focus on the sound, not just the letter. For example, "university" starts with a "y" sound (a consonant sound), so we use "a," even though it begins with the letter "u." Similarly, "hour" starts with a vowel sound (the "h" is silent), so we use "an."
