What does roc mean?
“Roc” is a word with two well-established uses. In medieval legend, it denotes a gigantic bird of extraordinary strength, often portrayed as capable of carrying off an elephant or other large animal. In modern English, it also names a form of rock music distinguished by elaborate arrangements, intricate instrumental work, and a strong emphasis on technical musicianship. The two senses are unrelated in origin, although both can convey a sense of power and magnitude. The legendary sense is now mainly literary, historical, or fantastical, while the musical sense is ordinary in descriptions of albums, bands, and musical styles. “Roc” is pronounced with the vowel sound of British “hot,” though speakers influenced by American pronunciation may use the vowel of “hot” or “law” depending on context.

Etymology of roc
The legendary bird entered English through medieval accounts of Eastern, especially Persian and Arabian, traditions. Its name comes through Middle English from a Persian form meaning a great or legendary bird, with related forms appearing in Arabic and other Middle Eastern languages. The separate musical sense is a shortening of “rock,” with the style’s name recorded in the mid-20th century.
How roc is actually used
In the bird sense, “roc” is literary and legendary rather than a standard zoological term. In the musical sense, it is normally lowercase and often functions as a modifier, as in “roc metal” or “a roc album.”
