How do you pronounce ‘cicada’?

A pronunciation crisis on a 17-year cycle—and how it got that way

Most pronunciation dilemmas arise with complete randomness, whenever a word happens to pop into the public consciousness. One point of confusion, however, is unique in that it strikes us with perfect biological regularity: How do you say “cicada”?

As people point in horror or wonder to the swarms of insects, should they say “si-KAY-da” or “si-KAH-da”? Or perhaps “chi-KAY-da” or “chi-KAH-da”? How did we get so confused? Should we, in the immortal words of the Gershwins, call the whole thing off?
