gung-ho

Etymology

It began as “Gung Ho”, the motto of the Second Raider Battalion of the United States Marines, introduced in 1942 by Lieutenant Colonel Evans F. Carlson,^{[1][2][3][4][5]} and is a borrowing from Mandarin Chinese.^[6][7][4] The Chinese phrase was the short name of the Chinese Industrial Cooperatives Society, founded in 1938.^[1][6][3] Carlson told his men that it meant "work together", but although its two syllables can be translated "work" and "together", they do not form such a phrase in Chinese: they are only the clipped form of the society's long name.^[1][6] Collins calls the word pidgin English,^[8] and Green's Dictionary of Slang instead derives it from a Chinese phrase meaning "awe-inspiring", literally "more fiery".^[2]

Earliest recorded meaning

The slogan of Carlson's Raiders, a US Marine guerrilla unit in the Pacific in the Second World War: 1942, in the New York Times Magazine of 8 November,^[4][5] which reported that Carlson often held what he called "kung-hou" meetings to thrash out problems.^[5] Merriam-Webster dates the word to 1941.^[9]

Semantic evolution

According to Merriam-Webster's Word Histories, the raiders soon called themselves and their spirit gung ho, while other marines used the word of them disparagingly, for obnoxious zeal; the praise and the sneer reached a compromise when the word passed into general use as "extremely or overly enthusiastic".^[1] Barnhart and Etymonline date that wider American use to 1959,^[10][5] the year of Saul Bellow's adverbial "gung-ho!" in Henderson the Rain King.^[2] Collins records a second sense, very keen to take part in military combat,^[8] and in Australian prison slang of 1990 gung hos were the guards of a security section known for their zeal.^[2]
