From what language does the word alphabet come

Etymology
The English word alphabet came into Middle English from the Late Latin word alphabetum, which in turn originated in the Greek ἀλφάβητος (alphabētos), from alpha and beta, the first two letters of the Greek alphabet.

Alpha and beta in turn came from the first two letters of the Phoenician alphabet, and originally meant ox and house respectively.

Informally the term "ABCs" is sometimes used for the alphabet as in the alphabet song (Now I know my ABCs ...), and knowing one's ABCs for literacy, or as a metaphor for knowing the basics about anything.
