  • noun an enjoyable experience or situation. An Americanism derived from the verb to groove (on) and the adjective groovy. The word was hip jargon of jazz musicians since the 1930s, later becoming part of the hippy lexicon and as such was also heard outside the USA until the mid-1970s. It now sounds very dated.
  • verb to experience a sensation of well-being, fellow-feeling, to feel in tune with one’s surroundings. This well-known and characteristic hippy term originates in the slang of jazz musicians and others for whom being in the groove meant being at one with the melody, with one’s fellow players, etc. (like a needle in the groove of a record). The word subsequently became a pivotal one for hippies, for whom it expressed a notion of enjoyable one-ness with one’s environment that hitherto lacked a name. The expression was hackneyed by the time James Taylor was ridiculed by British rock journalists for his declaration at a mid-1970s concert at the Royal Albert Hall that he ‘grooved to the vibes’. To ‘groove on something’ was another typical form.
