Recurring vs Reoccurring l Difference & Definitions

Recurring and reoccurring both mean “happening again” and are often used interchangeably. However, recurring generally implies the additional meaning of repetition, especially frequent or periodic repetition.

As an adjective, “recurring” is used much more frequently than “reoccurring.” We rarely need to use either of these words as present participles (i.e., verbs).

  • Use recurring to emphasize the regularly or periodically repeating nature of an event/occurrence (e.g., “a constantly recurring problem”).
  • Use recurring in mathematical contexts to describe a decimal with a digit or group of digits that repeats indefinitely (i.e., “a recurring decimal”).

Note
“Recurring” and “reoccuring” aren’t used as verbs very often, but if you need to use them as verbs to complete the phrase “prevent/stop something from [recurring/reoccuring],” use “reoccurring” if you mean “prevent from happening again even one time” (e.g., “It just can’t happen again; we have to stop it from reoccurring”).

Similarly, in progressive perfect tenses, use “reoccurring” to express that a repeating occurrence is/was “happening again” (e.g., “The issue was fixed but has been reoccurring recently”).

Reoccurring meaning

Reoccurring is the present participle of the verb “reoccur,” which means “happen again.” Unlike the verb “recur,” “reoccur” does not imply the additional meaning of frequent or periodic repetition. The same is true for the related adjectives “recurring” and “reoccurring.”

As an adjective, “reoccurring” is much less common than recurring because most things we need to describe as “happening again” are in contexts that involve frequent or regular repetition.

The word “reoccurring” is pronounced with the main stress on the third syllable [re-o-ccurr-ing].

Recurrent vs recurring

The adjectives recurrent and recurring both mean “happening repeatedly” and are often used interchangeably.

Recurrent is common in medical contexts (e.g., “recurrent disease/infection/fever”). In anatomy, it is also used with a different meaning, where it appears in the names of certain nerves and arteries that run in the opposite direction to other nearby structures (e.g., “the recurrent laryngeal nerve”).

Recurrent is also sometimes the preferred choice to emphasize the aspect of “returning from the past” rather than simply “repeating.”
