Aprox vs. Approx – Which is Correct?
“Approx” is the correct spelling and a widely used abbreviation of “approximately,” meaning “about” or “roughly.” “Aprox” is a misspelling caused by leaving out one “p.” Use “approx.” in informal or space-limited writing, but spell out “approximately” in polished prose when clarity and formality matter, especially in reports, essays, and emails.
Aprox or Approx – Which is Correct?
Approx is correct. It is an abbreviation of approximately and means “about,” “roughly,” or “nearly.” Aprox is incorrect because it omits one of the two consecutive ps found in the root word.
The spelling mistake usually results from phonetic confusion or typing quickly. When spoken, approximately does not clearly emphasize both ps, so writers sometimes shorten the word incorrectly as aprox. The accepted abbreviation is approx, often written as approx. with a period.
The Best Trick to Remember the Difference
Use the double-P reminder: approximately has two ps, so its abbreviation keeps both—approx. You can also remember the phrase “approx has a pair of p’s.” If you see aprox with only one p, it is missing a letter.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| aprox | Misspelling | Incorrect form of “approx” | Avoid writing “aprox. 20 minutes.” |
| approx | Abbreviation | Approximately; about; roughly | The journey takes approx. 20 minutes. |
How to Use Approx
Approx is an informal abbreviation of approximately. It is commonly used before numbers, measurements, times, distances, prices, quantities, and dates when the information is not exact. The abbreviation appears frequently in schedules, notes, charts, forms, technical documents, advertisements, and digital communication.
Both approx and approx. are seen in English. Style preferences vary: many formal style systems use a period because the abbreviation ends before the full word does, while some modern usage omits periods from common abbreviations. Follow the style guide used by your organization or publication.
In highly formal prose, it is usually better to write approximately in full. The shortened form is useful when space is limited or when the writing is practical and concise.
Example 1: The museum is approx. two miles from the train station.
Example 2: The repair should take approx. three hours.
Example 3: Approx 500 guests attended the outdoor concert.
Etymology of the Word Approx
Approx is a clipped abbreviation of approximately, which comes from the Latin approximatus, meaning “made near” or “brought close.” The English word approximately developed from the idea of being close to an exact amount. The abbreviation became popular as a space-saving form in practical and written communication.
Related Concepts
Understanding abbreviations and words expressing approximation helps clarify when approx is appropriate and why it should not be confused with an exact measurement.

- Exact numbers: An exact number communicates precision, while “approx” signals that the figure is estimated or rounded.
- Style conventions: Different style guides may prefer “approx.” or “approx” and may recommend spelling out “approximately” in formal writing.
