Hebrew letter MemMem (also spelled Meem, Meme, or Mim) is the thirteenth letter of the Semitic abjads, including the Hebrew alphabet. Mem is believed to derive from the Egyptian hieroglyphic symbol for water. In Hebrew, Mem, like Kaph, Nun, Pe, and Tzadi, has a final form, used at the end of words: its shape changes from מ to ם. In gematria, Mem represents the number 40 in both the Standard and Mispar Gadol Methods of Gematria; However, (mem sofit) final mem's value is 40 in the Standard Method and 600 in the Mispar Gadol method.
