Is Greek pronunciation hard?
Greek Pronunciation
Pronunciation can be a difficult task when learning any new language. Greek presents a particular challenge in that some letters of its alphabet look similar to English letters, but they are not pronounced the same.
How to pronounce κ?
Greek did not have a sound corresponding to our CH, so whenever you see CH in a Greek word, pronounce it like K. (That is why “chaos” is pronounced “kay-oss” and not “chay-oss.”) Greek also had a real K: the letter kapa (Κ κ). In pronouncing transcriptions, it is pronounced identically with chi: both are pronounced K.
How do you pronounce χ?
If you do not speak German or French, don't worry about it, just pronounce it the way the table suggests. Xi (χ): This is the same sound as "ch" in "Bach", which does not sound like "ch" in "chair".
