New pros backpack

The word backpack was coined in the United States in the 1910s. Moneybag and packsack were used before; they now occur mainly as regionalisms. The word rucksack is a German loanword mainly used in the UK and in the US Army: in German 'der Rücken' means 'the back' (the part of the body), and Sack for bag. The name Rucksack is cognate with Danish Rygsæk, Norwegian Ryggsekk, Dutch Rugzak, Afrikaans Rugsak and Swedish Ryggsäck. Alternative names include Haversack, and in German language called Kraxe (in 19th century the term kraxeln was used for climbing). (The term "haversack" more properly describes a small cloth bag on a strap worn over one shoulder, and used to carry one or more "havers" or havercakes or oatcakes.)
