Wiki article on this topic: Hockey is a sport in which two teams play against each other by trying to manoeuvre a ball or a puck into the opponent's goal using a hockey stick. There are many types of hockey such as bandy, field hockey, and ice hockey.
In most of the world, hockey refers to field hockey, while in Canada, the United States, Finland, Sweden, Latvia, the Czech Republic and Slovakia, hockey usually refers to ice hockey.
The first recorded use of the word hockey is in the 1773 book Juvenile Sports and Pastimes, to Which Are Prefixed, Memoirs of the Author: Including a New Mode of Infant Education by Richard Johnson , whose chapter XI was titled "New Improvements on the Game of Hockey". The belief that hockey was mentioned in a 1363 proclamation by King Edward III of England is based on modern translations of the proclamation, which was originally in Latin and explicitly forbade the games "Pilam Manualem, Pedivam, & Bacularem: & ad Canibucam & Gallorum Pugnam". The English historian and biographer John Strype did not use the word "hockey" when he translated the proclamation in 1720, instead translating "Canibucam" as "Cambuck"; this may have referred to either an early form of hockey or a game more similar to golf or croquet.
The word hockey itself is of unknown origin. One supposition is that it is a derivative of hoquet, a Middle French word for a shepherd's stave. The curved, or "hooked" ends of the sticks used for hockey would indeed have resembled these staves. Another supposition derives from the known use of cork bungs, in place of wooden balls to play the game. The stoppers came from barrels containing "hock" ale, also called "hocky".
Games played with curved sticks and a ball can be found in the histories of many cultures. In Egypt, 4000-year-old carvings feature teams with sticks and a projectile, hurling dates to before 1272 BC in Ireland, and there is a depiction from approximately 600 BC in Ancient Greece, where the game may have been called kerētízein or because it was played with a horn or horn-like stick. In Inner Mongolia, the Daur people have been playing beikou, a game similar to modern field hockey, for about 1,000 years.
