Lexicographer Jesse Sheidlower, the principal American editor of the "Oxford English Dictionary", argues that the terms "hipster" and "hippie" derive from the word "hip", whose origins are unknown. The word "hip" in the sense of "aware, in the know" is first attested in a 1902 cartoon by Tad Dorgan, and first appeared in prose in a 1904 novel by George Vere Hobart (1867–1926), "Jim Hickey: A Story of the One-Night Stands", where an African-American character uses the slang phrase "Are you hip?"
