Who started the word Groovy?

Answer 1

Often there is no specific inventor of words, or phrases, but some words are made by groups of people who agree on something and need a new word to express their feelings. Here is the etymology of the word groovy, from the Online Etymology Dictionary; unfortunately it doesn't say WHO started it: groove c.1400, from O.N. grod "pit," or M.Du. groeve "furrow, ditch," from P.Gmc. *grobo (cf. O.N. grof "brook, river bed," O.H.G. gruoba "ditch," Goth. groba "pit, cave," O.E. græf "ditch"), related to grave (n.). Sense of "long, narrow channel or furrow" is 1659. Meaning "spiral cut in a phonograph record" is from 1902. Fig. sense of "routine" is from 1842, often depreciatory at first, "a rut." Adj. groovy is 1853 in lit. sense of "of a groove;" 1937 in slang sense of "excellent," from jazz slang phrase in the groove (1932) "performing well (without grandstanding)." As teen slang for "wonderful," it dates from 1944; popularized 1960s, out of currency by 1980.
