Many learners feel confused between “occurring” and “occuring.” These words look almost the same, and the only difference is one extra “r.” Because of this, people often think both spellings are correct.
This confusion happens because English has rules about double letters, and they are not always easy to remember. Some verbs double the last letter when we add -ing, while others do not.
But don’t worry the rule for this word is simple once you understand it. This article will explain everything in very easy English so you can use the correct spelling with confidence.
Quick Answer
- Occurring = correct spelling (with double “r”)
- Occuring = incorrect spelling
✔ Correct: The problem is occurring again.
❌ Incorrect: The problem is occuring again.
👉 Always use occurring
