U+03C7 "χ" Greek Small Letter Chi is the twenty-second letter of the Greek alphabet, representing the voiceless velar fricative sound (as in the Scottish "loch" or the German "Bach") in classical and modern Greek, though its pronunciation varies in different linguistic contexts. In mathematics, science, and engineering, it is widely used as a symbol for variables, the chi-squared distribution in statistics, the chromatic number in graph theory, and the electric susceptibility in physics, among other specialized fields. Additionally, it appears in the Chi Rho monogram, an early Christian symbol formed by combining this letter with the Greek letter Rho.
