Our friends over at Flavorpill have posted a very interesting article that touches on the etymology of 10 musical genres, including ska and reggae.  According to the blog:

Ska: We know ska first appeared in ’50s Jamaica, but we’re still not sure who coined the term. Various musicians claim that it 1) refers to the “skat! skat! skat!” sound a guitar makes, 2) came about in 1959, when bassist Cluett Johnson told guitarist Ernest Ranglin to “play ska, ska, ska,” 3) that it evolved from Johnson’s typical slang greeting “skavoovie”, and 4) that musician an producer Byron Lee made it up.

Reggae: By the time Toots & the Maytals, who are credited with originating the term “reggae” in 1968 first named a song “Do the Reggay,” it was already known in Kingston as a slower version of rocksteady. It is thought to have evolved from rege-rege, which in its literal form means “ragged clothes” but also came to mean “a quarrel, protest.”
