Correct Use
Use unique when something is the only one of its kind, unlike others, or clearly special in a specific way. The correct article is a unique, not an unique, because unique starts with a “you” sound.

Meaning of Unique
Unique is an adjective. Its main meaning is being the only one or having no exact equal. A thing can be unique because there is only one of it, because it has a rare feature, or because it belongs to one place, person, case, or group. Merriam-Webster lists the meaning as “being the only one” and also gives the sense “without a like or equal.” Source-1✅
- Only one: “This is a unique record in the archive.”
- Different from others: “Her voice has a unique tone.”
- Special in context: “The museum offers a unique view of local craft.”
- Limited to a place or case: “This plant is unique to that valley.”
In everyday English, unique often means “special” or “unusual,” but its sharper meaning is one of a kind. That sharper meaning is useful in careful writing.
Correct Use of Unique
Use unique before a noun or after a linking verb such as be, seem, feel, or look. It usually describes a feature, item, chance, problem, style, name, design, place, method, sound, or quality.
Before a Noun
- She has a unique writing style.
- The store sells unique handmade cards.
- That recipe has a unique flavor.
After a Linking Verb
- This pattern is unique.
- The sound feels unique at first.
- His approach seems unique.
The word works best when the sentence shows what makes the thing different. “A unique design” is fine. “A unique design with a folding handle” is clearer.
A Unique or an Unique
The correct phrase is a unique. The form an unique is not the normal choice in standard English.
The reason is sound, not spelling. Unique begins with the sound /juː/ or /jʊ/, like the start of you. Purdue OWL explains that a is used before a consonant sound, while an is used before a vowel sound. Source-2✅
So the spelling starts with the letter u, but the sound starts like y. That is why English uses a unique.
Very Unique and More Unique
Many teachers and editors prefer not to grade unique when it means one of a kind. Under that stricter use, something is unique or it is not. So very unique, more unique, and most unique can sound loose.
| Phrase | Best Use | Cleaner Alternative |
|---|---|---|
| very unique | Casual speech when meaning “very unusual” | very unusual, rare, striking |
| more unique | Loose comparison | more unusual, more distinctive |
| most unique | Casual emphasis | rarest, most distinctive |
| almost unique | Useful when something is nearly one of a kind | almost unique, nearly one of a kind |
There is some room in real usage. Merriam-Webster notes that phrases like very unique appear when unique means “unusual” or “rare.” Still, in clean writing, very unusual often says the same thing with less friction.
Word Family and Forms
The word unique has a small word family. These related forms are useful, but they do not all fit the same place in a sentence.
| Form | Part of Speech | Meaning | Example |
|---|---|---|---|
| unique | Adjective | One of a kind; unusual in a clear way | This bowl has a unique shape. |
| uniquely | Adverb | In a unique way | The room is uniquely arranged. |
| uniqueness | Noun | The quality of being unique | The uniqueness of the pattern is easy to notice. |
Cambridge Dictionary lists uniquely and uniqueness as related forms of unique. Source-3✅
Common Mistakes Table
Most mistakes with unique come from the article before it, weak exaggeration, or using it when the sentence only means “nice” or “good.”
| Mistake | Why It Feels Off | Better Version |
|---|---|---|
| an unique idea | Unique starts with a “you” sound. | a unique idea |
| This is very unique. | Weak if the meaning is “one of a kind.” | This is unique. |
| This is more unique than that. | Sounds odd when comparing “one of a kind.” | This is more distinctive than that. |
| That was a unique good day. | Word order is unnatural. | That was a uniquely good day. |
| The product is unique and different. | The meaning repeats itself. | The product has a unique shape. |
Origin of Unique
Unique came into English through French, from Latin unicus, linked to unus, meaning “one.” That history matches the modern meaning: single, sole, one of a kind. Source-4✅
This also explains why unique feels stronger than words like nice, interesting, or different. It carries the idea of one-ness, not just quality.
