Synonym discussion

Sense: noun/3

Rocker is the most casual of these terms and can refer to any performer of rock music, from a garage-band singer to a stadium headliner. Rock musician is more formal and is often used in journalism or academic writing to describe someone's profession without implying fame. Rock star specifically means a very famous and successful rock performer who enjoys celebrity status, and it carries a connotation of wealth and adoration. Guitarist is a narrower term that focuses on the instrument rather than the genre — a guitarist may play jazz or classical, not only rock. For example: 'Jude is a local rocker who plays in a pub band' (informal performer), 'The rock musician gave an interview about her creative process' (neutral profession), 'The rock star arrived in a private helicopter' (fame), and 'The guitarist switched from a Fender to a Gibson mid-song' (instrument focus).

Etymology

Old EnglishEnglish

The word rocker comes from the verb rock (Old English roccian, meaning 'to move back and forth') combined with the suffix -er, which indicates a person or thing that performs an action. Originally, rocker referred only to the curved support that 'rocks' under a chair. By the 1600s it also meant the chair itself. In the 1950s and 1960s, as rock and roll music became popular, the term was extended to the musicians, fans, and songs of the new genre, and later to the British motorcycle-riding youth culture of the 1960s. The idiom off one's rocker (meaning 'crazy') dates from the late 1800s and may compare a loose rocking-chair rocker to an unstable mind.
