Which definition best describes sporadic?

• A. Occurring at irregular intervals; not constant or regular; patternless
• B. Not active
• C. A numerical fact
• D. A field of study

Answer: (A)

Sporadic describes events that happen irregularly, with breaks and no predictable pattern. It conveys that something occurs only occasionally and not on a steady schedule. This fits the definition of occurring at irregular intervals; not constant or regular; patternless.

So, this best matches how sporadic is used in real sentences, like sporadic rain showers or sporadic outages—things that don’t occur consistently. Other options describe being not active, a numerical fact, or a field of study, which are unrelated to the idea of irregular timing.
