Occurring at irregular intervals; not continuous or steady.

Describes a problem or phenomenon that appears and disappears, rather than being constant or continuous. This makes it particularly challenging to diagnose and fix.

The story behind the word. The word 'intermittent' comes from the Latin 'intermittere', meaning 'to leave off', 'to interrupt', or 'to break off'. This Latin verb is formed from 'inter-' (meaning 'between' or 'among') and 'mittere' (meaning 'to send' or 'to let go'). So, something 'intermittent' is literally 'sent between' or 'let go between' periods of activity, creating a stop-and-start pattern. It's a perfect description for those frustrating problems that come and go.

Word relationships

  • sporadic: Similar, but 'sporadic' often implies more irregular and scattered occurrences, while 'intermittent' can suggest a more regular pattern of stopping and starting.
  • periodic: Occurring at regular intervals; 'intermittent' is at irregular intervals.
  • occasional: Happening sometimes but not often; 'intermittent' emphasizes the stop-and-go nature.
  • continuous: Forming an unbroken whole; without interruption.
  • constant: Occurring continuously over a period of time.
  • steady: Firmly fixed, supported, or balanced; not shaking or moving.

Commonly confused with

  • glitch: An 'intermittent' problem describes the pattern of a problem (on-again, off-again). A 'glitch' is a type of minor, temporary problem. A glitch can be intermittent.
  • lag: 'Lag' is a continuous slowdown. 'Intermittent' describes something that stops and starts, which could include intermittent periods of lag or complete unresponsiveness.
