Pronunciation

  • IPA: /ˈɹɒk.ə(ɹ)/ (UK); /ˈɹɑ.kɚ/ (US)[1]

Etymology

It is formed from English rock + -er,[2][3] from Middle English rokker, rokkere (“one who rocks a cradle”),[2][4][5] from rokken (“to rock”) and -ere (“-er”).[4][5] The rock-music senses are from rock in its musical sense.[2]

Earliest recorded meaning

A nurse or attendant who rocks a child's cradle (14th century).[6][2][4]

Semantic evolution

From the person who rocks a cradle, the word passed to the things that rock.[6][7] In Scots the plural meant a cradle (1566).[6][7] From the 1760s it named one of the curved pieces fixed under a cradle or chair so that it can rock;[8][7] since 1836, first in the United States, a rocking chair itself.[7][2] Many devices that rock were later called rockers: a cradle for washing gold-bearing gravel, a skate with a curved blade, a mezzotint engraver's toothed tool, and parts of machines and engines.[7][3][9] The slang off one's rocker, crazy, is recorded from 1897;[6][10][2] Etymonline notes an earlier baseball phrase get off one's rocker, get busy (1895).[2] In American military insignia the curved stripe under a sergeant's chevrons has been a rocker since 1944.[11][7] With rock and roll came the senses of a rock song (1947) and a performer or fan of rock music (1958 in the Historical Thesaurus, 1963 in the OED),[7][6] and in 1960s Britain the Rockers, leather-jacketed motorcyclists who were rivals of the Mods.[2][10][12]
