Recur vs. Reoccur: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 24, 2023
Recur means to happen repeatedly or at regular intervals; reoccur means to happen again but not necessarily repeatedly or at regular intervals.

Key Differences

Recur and reoccur, though used interchangeably by many, carry distinct nuances in their meanings. "Recur" implies a patterned repetition, often at regular intervals. For example, birthdays recur every year. On the other hand, "reoccur" refers to something happening again but without the suggestion of a regular pattern. A rainbow, after a series of rainy days, might reoccur.
In the realm of grammar and lexicon, "recur" derives from the Latin verb "recurrere," which translates to "run back." This etymology hints at the word's sense of cyclicality. On the other hand, "reoccur" combines "re-" (meaning again) with "occur," indicating simply an event taking place once more without necessarily hinting at frequency or pattern.
Both "recur" and "reoccur" are verbs, and their usage often depends on the context and the desired specificity of meaning. When discussing events that have a predictable, cyclical nature, "recur" is more apt. For random or unpredictable repetitions, "reoccur" is more suitable.
Recur and reoccur might seem synonymous, given that both imply a return or repetition of an event. However, the subtlety lies in the inherent emphasis on regularity, pattern, or predictability. "Recur" inherently suggests a known frequency, while "reoccur" remains ambiguous about intervals or patterns.
