Alpha
Alpha (uppercase Α, lowercase α; Greek: άλφα) is the first letter of the Greek alphabet. In the system of Greek numerals it has a value of 1. It was derived from the Phoenician letter Aleph . Letters that arose from Alpha include the Latin A and the Cyrillic letter А.
In English the noun alpha is used as a synonym for "beginning", or "first" (in a series), reflecting its Greek roots.
