Etymology

recurrence = re<again> + curr<run> + ence<noun suffix>

  • re: Prefix meaning "again" (from Latin re-).
  • curr: Root meaning "to run" (from Latin currere).
  • ence: Noun-forming suffix indicating a state or quality (from Latin -entia).

Etymology Origin:
The word "recurrence" traces back to Latin recurrere ("to run back"), combining re- (again) and currere (to run). It entered Middle French as recurrence before being adopted into English in the 16th century. The core idea of "running back" metaphorically evolved into "happening again," reflecting cyclical or repeated events.
