The Origin of Recur or Reoccur

The word recur comes from the Latin word recurrere, meaning “to run back” or “return.” It entered English with the meaning of something returning again and again.

The word reoccur is formed from two parts:

• Re- = again
• Occur = happen

Therefore, reoccur literally means “to happen again.”
