English learners often struggle with small grammar details that make a big difference in writing and speaking. One common confusion is whether we should say “a unique” or “an unique.”

Understanding the rule behind a unique or an unique helps improve grammar accuracy, professional writing, and everyday communication. In this complete grammar guide, we will explain the correct rules, provide examples, show common mistakes, and give practice exercises so you can master the concept confidently.

The phrase “a unique or an unique” refers to choosing the correct indefinite article before the word unique.
