What does alphabetical mean?
Alphabetical describes anything arranged according to the conventional order of the letters of the alphabet — A to Z. It is most often applied to lists, indexes, catalogues, directories, and files, where placing entries in alphabetical order makes them predictable and easy to locate: names in a phone book, titles in a bibliography, or folders on a computer. The word can also describe something that involves or depends on an alphabet as a writing system, though this sense is less common. Alphabetical ordering carries connotations of tidiness, fairness, and impartiality — it imposes a neutral system rather than a judgment about importance — which is why competitions, waiting lists, and reference works so often use it. Closely related forms include the adverb 'alphabetically' and the verb 'to alphabetize', meaning to put into such an order. Derived from the Greek-rooted word 'alphabet', it entered English usage in the early modern period and remains indispensable wherever information must be organized for quick retrieval.

Most frequently used to describe lists, indexes, and filing systems.
Of or relating to an alphabet; using or expressed by an alphabet.
"Alphabetic and alphabetical notation systems underpin most modern writing."
This broader sense overlaps heavily with 'alphabetic'; the two are often interchangeable here.
The word 'alphabetical' is itself a near-perfect rhyme with 'mathematical' — and both trace back to the same ancient Greek love of ordered letters and numbers.

Etymology of alphabetical
Alphabetical derives from 'alphabet', which comes from the Latin 'alphabetum', itself borrowed from Greek 'alphabētos', formed from the names of the first two Greek letters, alpha and beta. The adjective form developed in English around the late sixteenth or early seventeenth century, alongside related forms such as 'alphabetic'. Its cognates across European languages — French 'alphabétique', Spanish 'alfabético', German 'alphabetisch' — all reflect the same Greek-Latin lineage.
