The silhouette of the open hand, with its radiating lines, discloses the origin of the letter K, “kaph,” which signified hollow or palm. We know that palmistry was practiced by the ancients, and probably the association of reading the hand and writing influenced the inclusion of this character. The Greeks added their favorite vowel sound, “a,” again and thus obtained their “Kappa.” The Romans had no need for this letter at first, as C furnished the same sound. When they did accept it, they made no change.
