The kanji 兆 is a pictophonetic character. The original form depicted a crack or a break, symbolizing a small beginning or the sign of something coming. The right side is a phonetic component, that gives the sound "chou". Over time, it came to represent a large quantity due to the idea of a crack/break signifying that something will appear in large numbers, ultimately leading to its meaning of a trillion.
