Other forms: occurrences

An occurrence is an instance of something or a time when something happens. If you get migraines, the doctor might ask how many occurrences of the headache you have in a month.

An occurrence is an instance of something that happens repeatedly. The occurrence of Lyme disease is more frequent in New England than it is in other parts of the country. As soon as authorities see an occurrence of rabies, they send warnings out to people who live in the area. Sometimes though, an occurrence is a single event or an incident. If you and your friend saw a ghost in the cemetery, that would be quite an occurrence!
