Alpha (uppercase Α, lowercase α; Greek: Άλφα Álpha) 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.
In "Brave New World "( Aldous Huxley) people are divided in groups from highly intelligent and well- educated humans to the people who are more or less considered to be stupid, simple-minded, retarded ones. Being an Alpha means that you belong to the highest class, the most intelligent one.
Amazing, but now I come to think of it: I don't know any European language that doesn't start with an A.
Hebrew starts with Alef. But how are the Asian languages? Do they have an alphabetical system like ours?
I also remember that we used alpha, bèta, gamma and delta in mathematics. Well I shan't make this too complicated. You will by now understand that Alpha is an important letter. An Alpha male among a group of animals is often the leader.
