Choose the appropriate indefinite article.
Understanding Indefinite Articles
Indefinite articles in English are “a” and “an”. They are used to refer to nonspecific items or people. The choice between “a” and “an” depends on the sound that begins the next word.
When to Use “A”
Use “a” before words that begin with a consonant sound.
Examples:
- a cat
- a dog
- a university (Note: “university” starts with a /juː/ sound)
When to Use “An”
Use “an” before words that begin with a vowel sound.
Examples:
- an apple
- an elephant
- an honor (Note: “honor” starts with a silent “h” and a vowel sound)
Special Cases
Some words can be tricky when deciding whether to use “a” or “an”. Pay attention to the sound rather than the letter.
Examples:
- a European (starts with a /j/ sound)
- an hour (starts with a vowel sound due to silent “h”)
- a one-time offer (starts with a /w/ sound)
Using Indefinite Articles with Acronyms and Abbreviations
When using acronyms and abbreviations, the choice of “a” or “an” depends on the pronunciation.
Examples:
- an FBI agent (starts with an /ɛf/ sound)
- a NASA scientist (starts with a /n/ sound)
