When writing in English, even small grammar choices can create confusion one of the most common being whether to use “a” or “an” before certain words. A frequently asked question is: should it be “a unique” or “an unique”?
At first glance, the answer may seem unclear because “unique” starts with a vowel letter. However, the correct usage depends on pronunciation, not just spelling. Understanding this simple rule can instantly improve your writing clarity and professionalism.
In this guide, we’ll break down the correct form, explain the logic behind it, and provide easy examples so you never get confused again.
Quick Answer
The correct phrase is “a unique,” not “an unique.”
This is because the word unique begins with a “yoo” sound, which is a consonant sound, not a vowel sound. In English, we choose “a” or “an” based on sound, not spelling.

2. “An”
