The chi ( Greek neuter Χῖ , Majuskel Χ, minuscule χ, standard pronunciation in the naming of the letter: [çi:] ) is the 22nd letter of the Greek alphabet and has after the Milesian system the numerical value of the 600th

In ancient times, this letter denoted an aspirated, voiceless velar plosive [kʱǐː̂] , which in later times was either [ç] ( I-sound ) or [x] ( oh-sound ). The pronunciation in modern Greek is either [ç] before e- and i-sounds, or [x] before a-, o-, u-sounds and before consonants. The pronunciation of school Greek is similar in Germany. Today's pronunciation [k] for Chi in some foreign words from Greek such as B. Chaos, choir, Christ , comes closer to the ancient Greek pronunciation than that usually taught in schools.
