Diamonds

Diamonds or  (four-colour deck) is one of the four suits of playing cards in the standard French deck. It corresponds to Bells in the German deck.

The original French name of the suit is Carreau; in German it is known as Karo.

In older German-language accounts of card games, Diamonds are frequently referred to as Eckstein ("cornerstone"). In Switzerland, the suit is still called Egge (=Ecke i.e. "corner") today. The term "Karo" went into the German language in the 18th century from the French carreau, which goes back to the Latin word, quadrum, meaning "square" or "rectangle".
