What word describes occurrences that happen here and there?

The word "sporadic" is used to describe occurrences that happen here and there, suggesting a pattern of irregularity and infrequency. When events are labeled as sporadic, it implies that they do not occur consistently but rather at separate intervals and with some unpredictability. This term conveys a sense of randomness and occasional appearance, making it distinct from terms that describe more regular or frequent occurrences.

While "intermittent" can also relate to something occurring at intervals, it tends to imply a more systematic or periodic nature than "sporadic." "Frequent" and "constant" imply regularity, with "frequent" suggesting occurrences at short intervals and "constant" meaning something that happens continuously without interruption. Hence, "sporadic" captures the essence of happening at unpredictable and scattered times, making it the appropriate choice for this question.
