Diamonds (suit)

In playing cards, a suit is one of several categories into which the cards of a deck are divided. Most often, each card bears one of several pips (symbols) showing to which suit it belongs; the suit may alternatively or additionally be indicated by the color printed on the card. The rank for each card is determined by the number of pips on it. Ranking indicates which cards within a suit are better, higher or more valuable than others, whereas there is no order between the suits unless defined in the rules of a specific card game. Unless playing with multiple decks, there is exactly one card of any given rank in any given suit. A deck may include special cards that belong to no suit, often called jokers.

Various languages have different terminology for suits such as colors, signs, or seeds. Modern Western playing cards are generally divided into two or three general suit-systems. The older Latin suits are subdivided into the Italian and Spanish suit-systems. The younger Germanic suits are subdivided into the German and Swiss suit-systems. The French suits are a derivative of the German suits but are generally considered a separate system on its own.

The Latin suits consist of coins, clubs, cups, and swords. They are the earliest suit-system in Europe, having been adopted from the cards imported from Mamluk Egypt and Moorish Granada in the 1370s. These Turko-Arabic cards, called Kanjifa, employed the same suits, but the clubs represented polo sticks. Europeans changed that suit as polo was an obscure sport to them. Ultimately the suits can trace their roots back to China where playing cards were first invented. The earliest card games were trick-taking games and the invention of suits increased the level of strategy and depth in these games. A card of one suit cannot beat a card from another regardless of its rank. The concept of suits predate playing cards and can be found in Chinese dice and domino games such as Tien Gow.
