The word "Spade" is probably derived from the Old Spanish spado meaning "sword" and suggests that Spanish suits were used in England before French suits.^[2]

The French name for this suit, Pique ("pike"), meant, in the 14th century, a weapon formed by an iron spike placed at the end of a pike.^[3] In German it is known as Pik. It corresponds to the suit of leaves   (Laub, Grün, Schippen or, in Bavaria, Gras) in the German-suited playing cards. In Switzerland, the suit is known as Schuufle ('shovel') and in many German regions, e.g., the Rhineland, as Schüppe/Schippe ('shovel').

The spade symbol is a very stylized spearhead shape, pointing upwards, the bottom widening into two arcs of a circle and sweeping towards the centre to then form a sort of foot.

Generally, spades are black. They form one of the two major suits in bridge (with hearts). In the official skat tournament deck, spades are green, assuming the color of their German-deck equivalent.
