intermittent

This term describes a pattern of stopping and starting, often suggesting an unpredictable or unreliable frequency. It is frequently used in technical or medical contexts to describe signals, fevers, or mechanical failures where the disruption is the defining characteristic. While similar to sporadic, intermittent often implies a recurring cycle rather than completely random occurrences. It carries a neutral to slightly negative tone, typically highlighting a lack of consistency that creates inconvenience or instability.
