What is the significance of the double Yud used as a stand-in for G-d's name?

  • Perhaps it refers to G-d Who gave both the Written Torah and the Oral Torah? Commented Jul 22, 2012 at 21:26
  • Although not so much connected to the significance the Rema in Yoreh Deah Siman 276 Sif 10 writes that the "Shem" that is written in Siddurim with "beis yudin v'achas al g'behen (2 yuds and one on top)" may be ereased if it's l'tzrich. The Shach in Sif-Katan 14 adds in the Piskei Maharei (as well as what the Darchei Moshe brings down) it's only if it's "l'tzrich gadol". You see from here this was already before the time of the Rema that the Shem was written in siddurim like this.

When you have two Yudin (or in Polish Jewish pronunciation, "Yidin" - also means "Jews") who get together on an equal level, neither of them putting themselves higher than the other, then you have Hashem's presence there. (The "Holy Jew" of Pshischa, cited in R' S.Y. Zevin's Sippurei Chassidim to Num. 14:20)


Rav Tzadok Hakohen from Lublin answers in his Sefer Takanas Hashavim that it may be the first Yud represents HAshems name the Tetragrammaton (The Shem Havayah). The second Yud is from the last letter of the name of Adnus.

    That is why most siddurim put a Sh'va under the first Yud (corresponding to the first vowel of the Tetragrammaton) and a kamatz under the second yud (corresponding to the last vowel in the shem Adnus).

    @Yahu The Shva is also the first vowel in Adnus; it just becomes a Chataf because of the Alef. You forget that the vowelezation of the Tetragrammaton is borrowed directly from Shem Adnus.

  • i.e. both names intertwined like this Yud - ALEPH - Heh - DALED- Vuv - NUN - Heh - YUD i think it's for kabalistic kavanot

From what I'd heard (YUtorah shiur on sheimos), the original version was a double-yud with a horizontal line on-top, which was supposed to look like a "vav." So yud + yud + vav = 26, same count as Yud-then-Heh-then-Vav-then-Heh, it was a non-sheimos way of indicating the Name.
