Compair or Compare: compare is the correct spelling. It means to look at two or more things and find their similarities or differences.
While writing an email, you type “Please compair these prices,” then that red spelling line appears under compair. The confusion is easy to understand because compare sounds like it ends with “pair.” However, the correct spelling is compare, not compair.
So, if you are writing an email, essay, report, or social post, choose compare. Once you learn the spelling pattern, this mistake becomes much easier to avoid.
Compair or Compare: Quick Answer
Compare is the correct spelling in standard English. Compair is a spelling mistake when you mean to examine two or more things.
For example:
- Correct: “Please compare the two prices.”
- Incorrect: “Please compair the two prices.”
Also, the same spelling stays in related forms such as compared, comparing, and comparison.
The Origin of Compair or Compare
The word compare has a long history. It comes from the Latin word comparare, which means to match or bring things together.
Over time, the word moved into French and then into English. The spelling settled around compar-, which is still seen in words such as comparison and comparable.
The spelling compair does not come from this word history. Instead, it likely feels natural because compare has a sound that is close to “pair.”
So, pronunciation can cause the mistake, but it does not change the spelling.
Compair or Compare Explained: Key Differences
The main difference is simple. Compare is the correct English word, while compair is an incorrect spelling when you mean “examine things side by side.”
| Term | Meaning | When to Use | Region/Context |
| Compare | Examine similarities or differences | Standard writing and speech | American and British English |
| Compair | Incorrect spelling of compare | Do not use for standard English | Not a standard regional form |
| Comparison | An examination of similarities or differences | When you need the noun form | American and British English |
| Compared | Past form of compare | When talking about a past comparison | American and British English |
| Comparing | -ing form of compare | When the action is happening | American and British English |
For example, you can say, “We need to compare the two plans.” However, you should not write, “We need to compair the two plans.”
The same rule applies in both American and British English. There is no standard British spelling called compair.

Common Mistakes with Compair or Compare
Several mistakes come from hearing the word instead of remembering how it is spelled.
Writing “compair” instead of “compare”
Mistake: “Can you compair these phones?”
Correction: “Can you compare these phones?”
This happens because the ending of compare sounds similar to “pair.”
Writing “compaired” instead of “compared”
Mistake: “We compaired the results.”
Correction: “We compared the results.”
Here, the wrong spelling carries over into the past form.
Writing “compairing” instead of “comparing”

When compare takes -ing, the final e is dropped.
Confusing compare with pair
Pair is a real word. It means two things that belong together.
However, compare has a different meaning. It means to examine things to see how they are alike or different.
For example, “I bought a pair of shoes” is correct. Meanwhile, “I need to compare these shoes” is also correct.
Writing “compair” because it sounds right
English spelling does not always follow pronunciation. Therefore, a word may sound one way but use different letters when written.
Remember compare, comparison, and comparable. These words all help you remember the compar- spelling.
