I promise not to ridicule you too much By all means, please explain; I'm totally interested and don't know enough to mock. However, as I am a novice when it comes to the Hebrew alphabet and its connection to tarot, you will need to take baby steps.
In the ordering of the Trumps, the Golden Dawn considered the Fool to be the 1st Trump, the Magician the 2nd, and so on to the last (22nd) Trump the World. In this order the Trumps are paired with the Hebrew alphabet taken in alphabetical order. Thus, the Fool is paired with the first letter Aleph, the Magician with the second, Beyt, and so on to the World with final letter Tav.
The Moon happens to be paired with Qoph, the 19th letter of the alphabet.
Correlating the Trumps with the Hebrew alphabet provides a connection between Tarot and Qabalah. The Hebrew alphabet is divided into three categories: the 3 Mother Letters (which are associated with the Elements Air, Water, and Fire), the 7 Double Letters (associated with the 7 classical Planets), and the 12 Simple Letters (for the 12 signs of the Zodiac). The 1st Simple Letter, Heh, is Aries. The 2nd, Vav, is Taurus. It continues thus through the Zodiac until we reach the 12th and final Simple letter, Qoph, which is Pisces. Thus we have the correlations Moon ~ Qoph ~ Pisces.
All this may seem quite complex and somewhat farfetched, but the system becomes more and more natural the more one works with it.
ETA. The Elemental, Planetary, and Zodiacal correlations of the alphabet are given in the Sefer Yetzirah, an early Kabbalistic document.
