cha-cha

The word "cha-cha" is a direct loanword from Cuban Spanish, where it originated as an onomatopoeic representation of the distinctive triple-step rhythm and the scraping sound of dancers' shoes on the floor. It emerged in the mid-20th century as a variant of the Cuban dance "danzón," influenced by the syncopated rhythms of the mambo. The name was popularized internationally by bandleader Enrique Jorrín in the 1950s, and the dance quickly became a staple of ballroom repertoire. Its formation follows a common pattern for naming dances, using reduplication to mimic a sound or rhythm associated with the movement.

This is a reduplicative onomatopoeic formation, imitating the sound of the dancers' feet or the rhythmic beat of the music. Its origin is Latin American Spanish.
