The Meaning of Occur and the Spelling of Its Forms
Occur has three meanings. It means "to be found or met with; appear," as in "a phenomenon that occurs around the world"; it means "to come into existence; happen," as in "an event that occurred on Friday"; and it means "to come to mind," as in "it occurs to me that the word is quite useful."
It's an unusual-looking word, being so small but with two c's up against each other, and then just a simple r at the end. The r is doubled, though, for the past tense: occurred. And the double r continues in the present participle: occurring.
The event is scheduled to occur at noon tomorrow.
No one was ready for what was about to occur.
There's a chance that a similar event will occur in the future.
