intermittent

Imagine a flickering lightbulb. It does not stay on steadily. It shines, then cuts out, then comes back again. That is intermittent. It describes something that happens again and again, but with gaps or pauses in between. A leaky faucet that drips now and then is intermittent. So is rain during a summer shower when it starts, stops, and starts again. You might also have an intermittent internet connection if your signal is weak.

The word comes from the Latin intermittere, meaning "to leave off" or "to interrupt." Think of something that keeps breaking off for a while and then returning. It often suggests that you cannot know exactly when the pauses will come or how long they will last.

Intermittent describes something that isn't continuous or consistent, but instead occurs at intervals with breaks or interruptions. Think of a heartbeat that occasionally skips a beat—it's not a steady rhythm, it's intermittent.

It is frequently used to describe things that are unreliable or unpredictable. For example: "The power supply was intermittent during the storm," meaning the electricity kept going on and off. Or, "He suffered from intermittent pain in his back," suggesting the discomfort came and went without warning.

Intermittent isn't necessarily about something stopping forever; it is about the "on-again, off-again" nature of an event. A weak radio signal might be described as intermittent if it fades in and out, or a person's presence at meetings might be intermittent if they only show up once in a while.

The context of usage is important. In technical fields like engineering or medicine, "intermittent" often has a precise meaning related to specific cycles and disruptions. However, in everyday language, it simply conveys the idea of something happening on and off, rather than steadily or predictably. It's about breaks in flow—moments of activity followed by periods of rest or absence. Whether you're describing a faulty machine, an unpredictable weather pattern, or a fluctuating feeling, intermittent highlights the lack of consistency and the presence of pauses within a process or experience.
