Recur or Reoccur – Quick Answer

Quick Answer:
Use “recur.” It is the standard and preferred word in both American and British English.

Meaning:
“Recur” means to happen again or to return repeatedly.

Examples:

What about “reoccur”?
“Reoccur” also means “to occur again.” However, it is less common and often avoided in formal writing.

The Origin of Recur or Reoccur

Understanding word history helps remove doubt.

Origin of “Recur”

The word “recur” comes from Latin recurrere, meaning “to run back” or “to return.”

“Re-” means “again.”
“Currere” means “to run.”

It entered English in the 15th century. Since then, it has been widely used in medical, academic, and formal writing.

Origin of “Reoccur”

“Reoccur” is formed by adding the prefix “re-” to the word “occur.”

“Occur” comes from Latin occurrere, meaning “to happen” or “to meet.”

Technically, “reoccur” is logical. It means “to occur again.” But English already had “recur,” so “reoccur” never became as popular.

That is why both words exist, but one dominates in usage.

British English vs American English Spelling

Unlike words such as “color” vs “colour,” this is not a major UK vs US spelling issue.

Both American English and British English prefer “recur.”
