Greek alphabet is a letter used in Greek, and it is also widely used in mathematics, physics, biology, astronomy and other disciplines. Greek letters are the earliest letters with vowels in the world. Cyrillic alphabet and Georgian alphabet used in Russian, Ukrainian, etc. Are all developed from the Greek alphabet.
