Cacophony Is a Noisy Word

If you’re hooked on phonetics, you may know that the Greek word phōnḗ has made a great deal of noise in English. Cacophony comes from a joining of phōnḗ ("sound" or "voice") with the Greek prefix kak- (from kakos, meaning "bad"), so it essentially means "bad sound." Other phat phōnḗ descendants include symphony, a word that indicates harmony or agreement in sound; polyphony, referring to a style of musical composition in which two or more independent melodies are juxtaposed in harmony; and euphony, a word for a pleasing or sweet sound. Kakos is responsible for far fewer English words, but one notable descendent is kakistocracy, meaning "government by the worst people," which, we'll be honest, doesn't sound great.

Synonyms

• noise
• roar
• rattle
• chatter
