Etymology

The word "alphabetical" derives from "alphabet," which itself comes from the first two letters of the Greek alphabet: "alpha" (Α) and "beta" (Β). The suffix "-ical" is added to form an adjective, meaning "pertaining to the alphabet." This construction reflects the logical progression from the naming of the letter system to describing things organized by it.
