When repeated, a dance

CHA

Think of the rhythmic sound often heard in lively Latin music and movement.

The word "cha" isn’t a dance on its own, but when you repeat it—"cha-cha"—it becomes the name of a lively Latin dance. The clue plays on this repetition, hinting that the answer is a short word that transforms into something familiar when doubled. It’s a clever way to turn a simple syllable into a well-known term.
