Alphabetical means arranged in the order of the letters. Alphabetical order, list them alphabetically, an alphabetical index.
It is the default way of ordering a list that has no other order, and it quietly advantages people whose names begin early in the alphabet — on ballot papers this has been measured and is real. Sorting rules differ between languages and cause endless trouble.

From alphabēticus + -al. by surface analysis, alphabet + -ical. alphabet comes from Middle English alphabete, from la-cla alphabētum. From Middle English alphabete, borrowed from la-cla alphabētum, from Ancient Greek ἀλφάβητος, from ἄλφα and βῆτα, the names of the first two letters of the Greek alphabet, Α and Β, lowercase forms α and β. The Greek names derived from aleph, the name of the phn - letter 𐤀 (“ox”) and beth, the name of the letter 𐤁 (“house”), so called because they were pictograms of those objects, having developed from the Egyptian hieroglyphs F1 (𓃾) and pr (𓉐). a doublet of alfabeto. Dipslaced native Old English stæfrǣw (literally "staff-row").
