Jan

Jan derives from the Latin Iohannes, itself from the Greek Ioannes, and ultimately from the Hebrew name Yohanan, meaning Yahweh is gracious. As a masculine name it is the standard Dutch, Scandinavian, Czech, Polish, and Sorbian form of John, borne by countless historical figures across northern and central Europe. In English it functions as both a feminine short form of Janet or Janice and a masculine medieval variant of John. Closely related forms include Johann, Johannes, Ivan, Iain, Sean, and Ján, the Slovak spelling.
