Packs with corner and edge indices (i.e. the value of the card printed at the corner(s) of the card) enabled players to hold their cards close together in a fan with one hand (instead of the two hands previously used[citation needed]). The first such pack known with Latin suits was printed by Infirerra and dated 1693, but this feature was commonly used only from the end of the 18th century. The first Anglo-American deck with this innovation was the Saladee's Patent, printed by Samuel Hart in 1864. In 1870, he and his cousins at Lawrence & Cohen followed up with the Squeezers, the first cards with indices that had a large diffusion.
Before this time, the lowest court card in an English pack was officially termed the Knave, but its abbreviation ("Kn") was too similar to the King ("K") and thus this term did not adapt well to indices. However, from the 17th century the Knave had often been termed the Jack, a term borrowed from the English Renaissance card game All Fours where the Knave of trumps has this name. All Fours was considered a game of the lower classes, so the use of the term Jack at one time was considered vulgar. The use of indices, however, encouraged a formal change from Knave to Jack in English language packs. Other languages faced similar problems when adding corner indices. In Romance languages both the King and Queen begin with the letter "R" while in Germanic and Slavonic languages they begin with the letter "K". Like the equivalent chess piece, the Queen was called Dame, Dama or other variations which mean "lady". Scandinavian cards have kept the "Kn" for knaves.
