NEWBIE

Its etymology is uncertain. It may derive from "newie", which is attested in U.S. and Australian sources of the 1850s, meaning a neophyte in a place or situation; alternatively, it may derive from the British public school slang "new boy" or "new blood", which is attributed to the same era and was applied to a schoolboy in his first term.^[4]

In the 1960s–1970s the term "newbie" had a limited usage among U.S. troops in the Vietnam War as a slang term for a new man in a unit.^[5]

Another use of the term newbee was the moniker given to new US Navy recruit students attending Basic Electricity and Electronics school by more senior students. A requisite course prior to enrollment in the A-school course at Naval Air Technical Training Center, Millington, TN.^{[citation needed]}

Its earliest known usage on the Internet may have been on the Usenet newsgroup talk.bizarre.^[6] The term is believed to have entered online usage by 1981.^[7]

Coming from an oral tradition, the term has various spellings. Among alternative forms are "newby", "nubie", and "newbee" (e.g. Los Angeles Times of August 1985: "It had to do with newbees. I could be wrong on the spelling, but newbees are the rookies among the Blue Angels...").^[4]

In 2009, "noob" was among candidates for the one-millionth English word selection by the Global Language Monitor.^[8][9]
