Which sentence uses the word 'sporadic' correctly?

• A. The weather is sporadic and constant.
• B. Sporadic meals occur on schedule.
• C. The meetings were sporadic throughout the year.
• D. The spelling of sporadic is incorrect.

Answer: (C)

Sporadic describes events that happen irregularly, with gaps or unpredictability rather than on a fixed schedule. The sentence about meetings fits this sense because it says the meetings occurred irregularly throughout the year, signaling occasional, non-systematic occurrences. The other statements clash with that meaning: describing weather as sporadic and constant contradicts the idea of irregular variation, since constant implies no fluctuation; claiming meals occur on schedule makes the timing regular, which is the opposite of sporadic; and saying the spelling is incorrect isn’t a usage example at all, especially since the word is spelled correctly in proper contexts.
