---

pe′ri·od′i·cal·ly adv.

Synonyms: periodic, sporadic, intermittent, occasional
These adjectives all mean recurring or reappearing now and then. Something periodic occurs at regular or unsurprising intervals: periodic disruptions in electricity. Sporadic implies scattered, irregular, unpredictable, or isolated instances: spies who could manage only sporadic contact. Intermittent describes something that stops and starts, often with no discernable pattern: heard intermittent gunfire in the distance. What is occasional happens randomly and irregularly: a retired celebrity still making occasional appearances in public.
