coon·can (knkăn′) or con·qui·an (kŏngkē-ən)
An early version of rummy for two players using 40 cards, in which the object is to meld all of the cards in one's hand in straights of 3 or more cards of the same suit or sets of 3 or 4 cards of the same rank.
[Alteration of American Spanish conquián, probably from Spanish con quién, with whom? : con, with (from Latin cum; see kom in the Appendix of Indo-European roots) + quien, whom (from Latin quem, accusative of quis, who; see kwo- in the Appendix of Indo-European roots).]
