The alphabet, alphabet of a language or language is the ordered set its letters.. It is also the group with a particular order, of the graphs used to represent the language serving as a communication system.
The word alphabet comes from the Greek ἀλφάβετον (alfábeton), derived from the first two Greek letters ἄλφα (alpha, α) and βῆτα (beta, β), derived in turn from the Phoenician letters ʾ alp and BET, which meant "ox" and "house" respectively. The Greek alphabet is an adaptation of the Phoenician alphabet, which also led others into Hebrew and Arabic. For its part, the term comes from Late Latin alphabet abecedārium, also derived from the name of the first letters, in this case four: a (a), b (be), c (ce) d (of).
