Kudos is derived from the Greek word κῦδος (kydos), which means "glory" or "fame." However, the word "kudos" itself is a relatively recent English borrowing from Greek, and the pronunciation in English is distinct from the original Greek pronunciation.
Here's how "kydos" is pronounced in Greek:
* ky as in "key"
* dos as in "dose"
Therefore, the correct Greek pronunciation of "kydos" is KEE-dos.
However, in English, we pronounce "kudos" as KOO-dos.
