Have you ever typed “openning” and seen a red spelling line appear under it? Many English learners and even native speakers get confused between “openning” and “opening.” The words sound almost the same, so it is easy to think both spellings are correct.
This confusion usually happens when people add “-ing” to verbs. In English, some words double the last letter before adding “-ing,” while others do not. For example, “run” becomes “running,” but “open” becomes “opening.” Because of this rule, many people mistakenly write “openning.”
People search for “openning or opening” because they want the correct spelling for emails, essays, business writing, social media posts, and school work. Using the wrong spelling can make writing look unprofessional.
In this guide, you will learn the correct spelling, the reason behind the mistake, differences between British and American English, common errors, and real-world examples. By the end, you will know exactly when and why to use “opening.”
Openning or Opening – Quick Answer
The correct spelling is “opening.”
❌ Openning → Incorrect
✅ Opening → Correct
Examples:
- ✅ The store is opening tomorrow.

- ❌ The store is openning tomorrow.
The word “opening” comes from the verb “open.” Since “open” ends with two different consonant sounds, English grammar does not double the “n” before adding “-ing.”

The Origin of Openning or Opening
The word “open” comes from Old English openian, which means “to uncover” or “make accessible.” Over time, the word became “open” in modern English.
The spelling confusion appears because English has rules for adding endings like “-ing.”
For many short verbs with one vowel and one consonant, the last consonant doubles:
- Run → Running
- Sit → Sitting
But words like “open” do not follow this rule because the stress is not on the last syllable.
Correct form:
- Open → Opening
Incorrect form:
- Open → Openning
This is why “opening” became the accepted spelling in standard English.

Conclusion
The confusion between “openning” and “opening” is very common, especially for English learners. Even though “openning” may look correct at first glance, it is actually a spelling mistake. The correct form is always “opening.”
This happens because English spelling rules can be tricky. Some verbs double the final consonant before adding “-ing,” while others do not. Since the stress in “open” is not on the final syllable, the “n” does not double. That is why we write “opening,” not “openning.”
Both British English and American English follow the same spelling rule here, making “opening” the universal choice worldwide. Whether you are writing emails, business content, social media posts, essays, or news articles, “opening” is the correct and professional spelling to use.
A simple way to remember this is:
One “n” in “open,” one “n” in “opening.”
Using the correct spelling improves clarity, professionalism, and confidence in your writing.
