The yod is conceptually an infinitesimally small dot. That is difficult to draw and even harder to see, so the yod is used to represent it. To the Greeks it is the iota. In English we call it a jot. It represents the first idea that God had for creation. It is pronounced ''yah'';one of the names of God, and is a vowel, using only breath to form the sound. It signifies that God is spirit (the same word as breath).
