χι
chi/çi/
In Greek, chi is χι, the name of the letter written χ.
χι is the name of the twenty-second letter of the Greek alphabet. The idea of chi as a life force or vital energy comes from Chinese tradition, and Greek has no native word for it, so the borrowed name is usually written out as in English.
Meaning: the name of the Greek letter Χ (letter)
How do you pronounce it?
Romanized it is chi, and in IPA it is /çi/. The first sound is not the hard k of English chi but a soft breathy sound, like the h at the start of huge.
What mistakes should you avoid?
Do not pronounce χι like the English word chai or with the ch of chin. The Greek sound is a soft breathy one made near the roof of the mouth.
Did you know?
- While χι is the name of the letter, its sound evolved over millennia from a rough aspirated 'k' in Ancient Greek to the breathy sound used today.
- The name χι is derived from the Ancient Greek word χεῖ.
- While the letter χ is used in many Western words, the Greek way of saying its name χι sounds nothing like the 'ch' in 'character'.
Examples in context
- Πάω να γράψω το χι στο πίνακα.I am going to write the chi on the board.
- Γράψε το χι στο τέλος της λέξης.Grapse to chi sto telos tis lexis.Write the chi at the end of the word.
