What Does An Unique or A Unique Mean?
Meaning
The adjective unique means one of a kind, unusual, distinctive, or unlike anything else.
Examples:

Why People Confuse These Words
Many people believe that words beginning with the letter u automatically require an.
That assumption works for some words:
- an umbrella
- an uncle
However, article choice depends on pronunciation, not spelling.
The word unique starts with a “yoo” sound, which is treated like a consonant sound.
Because of that pronunciation, English grammar requires a unique, not an unique.
Grammar Rule Behind the Difference
The rule is simple:
- Use a before a consonant sound.
- Use an before a vowel sound.
Examples:
| Correct Article | Word | First Sound |
|---|---|---|
| a | unique | yoo |
| a | university | yoo |
| a | European | yoo |
| an | umbrella | uh |
| an | uncle | uh |
Examples in sentences:
- He offered a unique explanation.
- They found a unique approach to the project.
This pronunciation-based rule is recognized by the Oxford English Dictionary, Merriam-Webster, and Cambridge Dictionary.
