recur
UK: rɪˈkɜː(r) | US: rɪˈkɜːr
vi. to happen or occur again, especially repeatedly or periodically
vi. (of a thought, image, etc.) to return to the mind
vi. (mathematics) to repeat in a predictable pattern
The word "recur" originates from Latin recurrere, combining re- ("again") and currere ("to run"). The imagery of "running back" or "returning" evolved into the modern sense of repeated occurrence, whether in events, thoughts, or mathematical sequences. The logic ties physical motion (running) to abstract repetition.
