This thread will over a period of time deal with the history and meaning of the first five letters of the alphabet and this is something that everyone should know.
The English word alphabet came into Middle English from the Late Latin word alphabetum, which in turn originated in the Greekἀλφάβητος (alphabētos), fromalpha and beta, the first two letters of the Greek alphabet.[4]Alpha and beta in turn came from the first two letters of the Phoenician alphabet, and originally meant ox and house respectively.
