Reoccurs

Reoccurs is a verb meaning to happen again after a previous occurrence. It is the third-person singular present tense of the verb reoccur, and it is used to describe events, conditions, or phenomena that repeat or reappear after an initial instance. The prefix re- signals repetition, while occur is the core verb from which the form is built. Related noun forms include reoccurrence and recurrence; recurrence is more commonly preferred in formal writing, while reoccurrence is also widely understood.

Usage notes: Some editors prefer recurs as a more concise equivalent when describing something that happens again as a regular or inherent pattern. Reoccur, reoccurs, and reoccurrence are common in everyday usage, though some style guides discourage reoccur due to debates about redundancy. The choice among reoccurs, recurs, and recurrence often depends on cadence, register, and the specific meaning: reoccurs tends to emphasize the act of happening again, whereas recurrence emphasizes the ongoing or cyclical nature of the event.

Examples: The problem reoccurs after software updates. The symptoms recur in many patients. The recurrence of the error was noted in the monitoring log.
