U+03A7 "Χ" Greek Capital Letter Chi Unicode Character
Unicode Version 17.0
U+03A7 "Χ" Greek Capital Letter Chi is the uppercase form of the 22nd letter of the Greek alphabet, representing the "kh" sound as in the Scottish "loch." In modern Greek, it is pronounced as a voiceless velar fricative (like a hard "h"), while in ancient Greek it was aspirated, similar to a "k" with a breathy release. The letter's shape, often depicted as a symmetrical X, is widely recognized in academic and cultural contexts, such as in the abbreviation "Xmas" for Christmas, where Chi serves as the first letter of Christ in Greek, and in mathematics and science where it denotes various concepts, including the chi-squared distribution in statistics. Its uppercase form is visually identical to the Latin letter X, though distinct in Unicode encoding for proper text processing and historical accuracy.
