发音与拼写Pronunciation & Spelling
Words ending in '-adic' (nomadic, monadic, dyadic, triadic) rhyme with sporadic: all have the stressed /ædɪk/ ending. However, the first syllable of sporadic is /spɝ/, not /spɔːr/, so spelling lookalikes spore and sport (both with /spɔːr/) and the near-synonym spasmodic /spæzˈmɒdɪk/ do not rhyme with it.
