Etymology
the word "rocker" is a straightforward english formation, combining the verb "rock" with the agent suffix "-er." the verb "rock" itself has old english origins, deriving from roccian, which meant to move something back and forth. this sense of motion is central to the word's primary meaning, referring to the curved piece enabling movement on a chair or cradle. over time, the "-er" suffix extended the meaning to denote a person associated with the action, leading to its modern application for an enthusiast or performer of rock music, a genre named for its "rocking" rhythm.
